The Smart Moisture Sensor solution uses the RL78/G11 MCU's moisture sensor to measure the conditions of soil, and transfer the data to a smartphone app via an RL78/G1D Bluetooth Low Energy (BLE) module which can be graphically shown. For example, the app can provide a moisture vs. temperature graph. Additionally, the Smart Moisture Sensor can control a water valve by outputting a motor signal. The system also includes a buzzer to warn users if the soil becomes too dry.
