Temperature and Humidity DHT11 Sensor to Raspberry PI

* Field 1-3: Solar panel 50x50mm (2V, 70mA), D1 Mini Pro in DeepSleep (4min) and ESP-Now. Sending to ESP32 (gateway) which logs to ThingSpeak. * Field 4-8: Solar panel 100x60mm (6V, 1W), D1 Mini in DeepSleep (5min) and WiFi logging to ThingSpeak.

Collection of readings from different sensors.

Home environment monitoring system. Sensors will measure particulate matter (Ultrafine dust PM2.5 and fine dust PM10), co2, TVOC, ambient light, humidity, temperature and barometric pressure.

Temperature in Nea Kallikrateia, Chalkidiki, Greece. WiFi Sensor (ESP8266-DS18B20)

Hey I've moved house. I'm now in Bathgate and this device is in the converted attic space. At the start of June 2020 it's measuring 28C in there with a humidity around 45%. That's too much for my "office space" so I'm getting some venting sorted out.

Greenhouse monitor

temperature, accelerometer, color

Measured on the shaded north side of a building in Andover, Massachusetts, USA. Both F and C values are provided.

Uses a D1 Mini and Arduino code with an HTU21D for ambient sensing and two DS18B20 OneWire sensors for inlet and outlet temperature measurement. The heat-pump mode detection uses temperature difference and its derivative of the inlet and outlet temperatu
