## Features

* Running on Espressif ESP32 Microcontroller ([HiLetgo ESP-WROOM-32 ESP32 ESP-32S Development Board](http://www.hiletgo.com/ProductDetail/1906566.html))


  (Compatibility to Raspberry Pi was planned, but is currently broken.) 

* Software coded in [MicroPython](https://micropython.org/), must be copiled to bytecode [(__*.mpy__)](https://docs.micropython.org/en/latest/reference/glossary.html#term-.mpy-file) for ESP32

* Plant status monitorig

    * via Xiaomi Mi Flora Plant Sensors (Bluetooth Low Energy)

    * via capacitive Soil Moisture Sensors (wired)

* Tank low / Tank empty Status Monitoring with XKC-Y25-T12V (Non-Contact Liquid Level Sensor)

* Temperature Sensor [DS18B20](https://www.maximintegrated.com/en/products/sensors/DS18B20.html) (optional)

* Weather (i.e. Temperature, Barometric Pressure and Humidity) Sensors (optional)

    * [BME280](https://www.bosch-sensortec.com/products/environmental-sensors/humidity-sensors-bme280/)

    * [M5Stack ENV III](http://docs.m5stack.com/en/hat/hat_envIII) 

* Pump Control (5 or 12 Volts) with [Infineon BTS117](https://www.infineon.com/cms/en/product/power/smart-low-side-high-side-switches/low-side-switches/classic-hitfet-24v/bts117/) _N channel vertical power FET in Smart SIPMOS® technology_

* Automatic and manual Irrigation Control with one or two Pumps

* Power Supply from [Solar Power Manager](https://www.waveshare.com/wiki/Solar_Power_Manager) with Lithium-Ion Battery and [6 V/5 W Solar Panel](https://www.waveshare.com/Solar-Panel-6V-5W.htm) (optional)

* Battery Voltage Monitoring (optional)

* Controlling and Monitoring via MQTT over WiFi

## Dashboard with [IoT MQTT Panel](https://snrlab.in/iot/iot-mqtt-panel-user-guide) (Example)
