The IoT Plant Monitor measures temperature, humidity and soil moisture levels and transmits the data to the Blynk IoT cloud.
A mobile phone app can then be used to monitor the data and view both historical and real-time updates.
The prototype was built using
ESP8266 Arduino shield (a WiFi enabled SoC)
Soil Moisture Sensor
AM2302 Humidity Sensor Module.
USB Serial to TTL module for programming
Blynk IoT Cloud service
