I learned how to program ESP8266 so I created my first temperature IoT ESP8266 project. I used DHT22 as a temperature and humidity sensor and also I did some testing of power consumption using LIGHT SLEEP[…]
I have just made a prototype of ESP8266 (ESP-01) IoT temperature & humidity SI7021 sensor and also 2x three pin soil moisture sensors with only 0.006mA (6µA) current drain during the sleep.
You can find several breadboard adapters for ESP8266 WiFi module or nRF24L01+ RF transceiver and also several DIY manuals how to create your own, but I decided to use my new WiFi WSP8266 and NRD24L01 as soon[…]
