ESP8266 wifi soil moisture sensor for ambient temperature and humidity
What is it?
ESP8266 based soil moisture sensor Wi-Fi enabled. Also provide ambient temperature and humidity sensor.
At the sensor's heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. This microcontroller contains a Tensilica chip core as well as a full WiFi stack. You can program the microcontroller using the Arduino IDE for an easy-to-run Internet of Things core. You can use ESP flasher that an upload code at a blistering 115200 baud for fast development time. It also has auto-reset so no noodling with pins and reset button pressings.
The sensor can upload sensor datas to remote server. We provided example code for uploading to thingspeak.
The project is modifying of the I2C Moisture Sensor project from Miceuz. Thanks for his source code.
What's difference with rev 1.0?
Replace the DHT11 to TMP112 with I2C
Add a jumper for wire GPIO16 and Reset pin
Add a SWITCH for measuring soil sensor or battery voltage
