Addressable Temperature Sensors

#1 Post by prairietech » 24 Mar 2020, 21:52

I have an application where RFLink might work. It involves using 6-8 temperature sensors in different close proximity locations.
Does anyone know of any off the shelf weatherproof temperature sensors that are addressable so their temperature data can be decoded on a individual sensor output?
This would be for use in the USA in case frequency coverage is an issue.

If it is in (relative) close proximity, why not use Dallas 1wire sensors?

Running wire between the locations is not practical. In a couple locations, there is a driveway between sensor locations.

Should the sensor units be battery powered?
If not, then you can also have a look at ESPEasy and install several of them.

For battery powered ones I don't have a model to suggest.

I'm a HUGE fan of esp easy!
But yes I was looking for something battery powered.
Also was looking for something with better range than wifi. I've used Wemos, esp8266 and sonoff devices with very very poor range.

Well I recently added support for LoRaWAN via the Microchip RN2483, so a range of several km is also an option and on location you could share the values via p2p protocol (one as AP, the others as wifi client)

Still not a battery-powered solution as WiFi + battery is not a good solution.

Looks like the RN2483 is only available as a standalone radio chip? Any ESP devices running it imbedded?
I thought it would be an advantage to find an existing temp sensor already in a rain proof enclosure with a battery. Instead of having to create my own design with individual components. So far I have struck out.

Well there are Bluetooth sensors available, but not sure how far those reach.
These can run quite long on a coin cell and are quite small. Some even have a plug-able external temp sensor (probably using a 1Wire Dallas)
If I'm not mistaken, RpiEasy has support for Bluetooth sensors?
