• Project URL: AGRISMART , Greenie Realm

The initial purpose of this project was to pack all of my previous skills gaining from the Dr.ESP32 and Smart-clock-thermometer-hygrometer projects. Agrismart serves as a controller hub to monitor the soil moisture, temperature and humidity of an area of garden and control the water pump to water the plants. It is battery-powered and can be charged via solar panel and USB-C cable. Agrismart stays in deepsleep to preserve power, and wakes up every hour to update the sensor data to a LAMP server via WiFi hosted on a Raspberry Pi 4B, named Greenie Realm. BLE serves as a means to configure the WiFi credential, name, location, for the device either from smartphone or Greenie Realm. The PCB has been revised through 3 versions until it is terminated for the upcoming Agris project.
