Hi, I have three sensors: 2 BME280 pressure, temperature and humidity sensor and 1 HTU21D temeprature and humidity. I can read all of them since they use different I2C addresses (the BME280 can be configured with two different addresses). I am using Thingspeak as data repository. However, there is a...

Hi, I am interested in making environmental sensors. One hot topic in this field is dust /pollution sensors . Among the available low cost modules thare is the DSM 501 sold for about 7 euro by aliexpress DSM501.jpg This sensor has two outputs, one for PM1.0 and one for PM2.5 The outputs are digital ...

Hi, I have just recently switched to ESPeasy and I have upgraded my working hardware : 1 ESP8277 07 with 1 DHT22 (temp & humidity) , 1 DHT21 (temp & humidity), 1 SHARP GP2Y10 (dust sensor) and 1 DSM501A (PM1.0 and PM2.5 dust sensor). Previously all the data where sent to a private channel on...

I recently found easyESP and I am very happy of what has been done. I have developed several sensor applications using Arduino and lately the ESP8266. I am interested in home sensing and controlling and also in environmental monitoring. I have some experience in electronics, both analog and digital,...
