Let's Control It

For years have used the SDS011 Dust-sensor in the 'official' Luftdaten-configuration, in combination with BME280/DHT22. However, some months ago the setup broke-down, and no revival if reflashing & restarting. Now question: which part is at fault? 'No reflash possible' seems to hint that the NMC...

This weekend's bright, sunny, cloudless days with high light level invite for more testing, but first need response from the RFLinkStuntteam with firmware-update from v49.4, otherwise just 'repeat'.

Would car paint be a longer-lasting, DIY, water-resistant cover?
To be tested with next batch of replacement-DS18B20s.

Ton_vN

Sometimes just have to wait till 'nature' is offering the proper test-conditions with you in vicinity & able to test.
That may take significant time, causing late reactions:
see the run-up to this reaction on test-version v49.4

Ton_vN

It took quite long time to get perfect weather for this test, but recently a few continuously very bright & very clear days gave opportunity to make 'unspoiled' loggings of the transmission for highlevellightdata from the WS7000-Controller towards the RFLinkGateway. Analysis of the best logging ...

Ton_vN

For correct understanding, the present configuration is: - above soil is 1*SHT15, which has end-of-life, because humidity element totally failing, and thermo-sensor erratic (but no 100% replacement available anymore) - the 6 other thermosensors located from surface to -100cm downwards are DS18B20 in...

Ton_vN

Today the DS18B20s at -50cm and -100cm again failed.
For deepsoil-sensing have to find a thermo-sensortype which is better waterresistant, because raising/replacing every 3 months is not an acceptable way of life.

If interested in the movements of your house (or earth in general), perhaps this function running on a Raspberry is of some interest.
Probability that earth moves seems siginficant for the region you live, although at this moment it looks quiet in this picture.

@Dick60, In your message of 17:02 , I read Als paralel to the potmeter I connected the Sensor. Turning the Potmeter I see a change in messurments but putting the sensor in the wet soil, no difference is messured. Don't parallel connect, because then you only see the potmeter which probably is 'more ...

Now an 'all-electric' house, meeting all new Building & Conservation Rules?

Further experience described here

Ton_vN

More experience. After recent downpours the DS18B20 at -50cm went haywire, but during subsequent dry weatherintermittently returned'. Reason to pull/raise the whole array once more for inspection. Observations: - the 3 drains physically tight below each DS18B20 at -10cm , -20cm and -30cm did their ...

Might be a hardware aspect. Sounds strange, but USB-cables are not all identical, and that is not visible from outside: - some are sold for power supply only (and only have 2 cores for 0/GND and 5VDC) - others are fully equipped for transfer of power&data. - quality of manufacturing might be an ...

Observation / side-effect / learning-curve. . The grid-PCB of the rain-sensor is unheated. The blue line in the graph clearly shows what happens when frost arrives in combination with fog: - till 21:00 foggy & temperature is above 0, and the grid gets moisty => low impedance => high signal - fr...

Both sensors GY-63 in dry environment and under same ambient pressure (of approx. 1000mb)?

Ton_vN

@TDer

Completely agreed, and reason/background for the italic text in line 3:
it is a practical circumvention of the problem of clamping, nothing better than that.
My feeling is that the proper solution is described in line 2 of my previous message, but that takes time ......

Ton_vN

The proper solution is: research & test, finding the source of the problem and subsequent correction of related firmware. However, it involves at least 2 elements (WS7000P19-Controller and RFLinkGateway) and bright light (> 100kLux) is needed for reproduction of the problem. Not nice, but very p...

Collateral harvest of experiment with LeafWetness-sensing: capacitive moisture sensor experimentally installed as leafwetness-device. Reading by PCF8591 [=4* 8bits ADC]. Results (just for info) : 1) Read-out from LDR clearly identifies daylight-conditions 2) Read-out by capacitive sensor makes sense...

Ton_vN

Not an urgent matter, but just for an easy 'repair':
SHT11 and SHT15 having passed end-of-life, is a pin-compatible, modern replacement available?

[Otherwise have to find howto fit to ESPEasy a readily-available I2C-variant like SHT31]

Ton_vN

:o 'Old technology' sometimes useful for a better solution. The setup with 1 diode (D1) did not yield sufficient signal level to the ADC. The addition of a second diode (D2) improves/stabilizes the rectification of the incoming square wave signal so much that an amplifier is superfluous. . PWM_Vocht...

Some exercise with Taskrun and timers, resulting in some simple code doing a job ....... Timer1 is doing that job. Timer2 included to force a delay after reading the SHT15. Transmission to Domoticz probably redundant relative to setting under 'Devices', but in this way the read-out has a directly re...

Step-by-step check/elimination/correction of possibly problematic aspects. To see whether and how fast a readout could be done with related transmission to Domoticz, ran this test-script ( not useful for any other purpose, because of bad design for the loop: just a very rude experiment, nothing else...

Ton_vN

;) Clear that still a lot of learning curve required ....... Following simple script should do read-out/ 5 minutes, but see time-gaps longer than 5 minutes. Who might be 'guilty': script-error or SHT15-failure? On System#Boot do //When the ESP boots, do timerSet,1,10 //Set Timer1 for the inital even...

Ton_vN

Reading of SHT15 is still being performed, but with rather erratic timing. In that perspective perhaps clearer formulation of the question in previous message: is it possible to force a controlled reading of SHT15 by means of a Rule (or other type of 'kicking')? Rebooting of ESP8266 has effect, but ...

'Neighbouring' ESP8266 already in planning, but not yet present at location: therefore time for uncritical experimentation with this 'survival'-SHT15. Also alternative setup upcoming with DS18B20 for soil-temperature and PWM-sourced forksensor for soil-humidity. Reading SHT15 is Task2 at the ESP8266...

Now testing for some days with the renovated setup. Graph includes readings by 3 'real' meteo-sensors: Nexus at +20cm, WS7000P +10cm and WS7000 at -10cm (by means of thermoprobe) The probe of the WS7000-setup is running down through the yellowish pipe visible at right in background in the picture of...

Soilthermometers now under test, have the impression that the reducing lightinput at this time of the year starts to cause dips in the solar-powered supply.

8-) Back to Basics, in a very low power playground 'on square-cm' ...... In the interface-circuit , the elco C2 needs charging, to be seen by the ADC. Reduced the size of C2 to 100uF for quicker (dis)charging. The higher the input voltage to C2, the better: - with single Si-diode hardly signal seen ...

Ton_vN

Also stating that an MC-cell has 23% efficiency is 'rather' optimistic (for that price-tag).

Ton_vN

@TDer, Elco C0 in the circuit already blocks any DC-flow, but pure capacitive measurement indeed is preferred: at this moment a capacitive pen-sensor is in another trial as rain/leafwetness-indicator. IMHO basically any setup of the kind described in this thread is not very serious, but more for low...

Ton_vN

The DS18B20-sensors usually have a cable of max. 1m => in my array the deepest sensor at -100cm therefore needed an extension to reach the nearest junction box.

TD-er, All outdoor DS18B20s in my configuration have been delivered with steel holder.

Because liquid often follows gravity, one ...

Learning by experience. Testing is the start, to be followed by repair. 'Remote restauration' is not possible, and therefore dug the array with the 4 failing DS18B20, and possibly found the reason for their 'strike': the 32mm PVC-pipe used for bringing the sensors&cable down to their levels was ...

ZE25-O3 is easily available at AliX. by several suppliers, for prices between Euro30 and Euro75 per device. If DIY-assembly at least you have to invent housing & airflow and interfacing. Some further research into the characteristics of ZE25-O3 reveals that besides an UART-interface it also has...

Some extra protection also helps.
