# FloraGrow [![stability-release-candidate](https://img.shields.io/badge/stability-pre--release-48c9b0.svg)](https://github.com/mkenney/software-guides/blob/master/STABILITY-BADGES.md#release-candidate)

### Overview
This project revolves around the topic of smart irrigation in smart homes. First release is a power supplied soil moisture sensor (Sense PS). It connects via MQTT to an IoT software such as Home Assistant, ioBroker, Node-RED or similar. Later, there will likely be a variant that is powered by a battery and a valve controller with flow meters to complete the irrigation system.

### Features of the Sense PS
- Measurement of soil moisture and device temperature
- WiFi connection to an MQTT broker
- ESP32-C3 Super Mini DevBoard
- wide range power supply input 5...40V DC
- 3D printed housing
- strain relief
- epoxy resin encapsulated electronics to meet outdoor requirements
- usage of standard components

### Schematic
The schematic is quiet simple, only a few devices are put together.

### PCB
The PCB has two layers with planes for 3.3V on top and GND on the bottom side. It is populated from both sides to achieve a compact form factor. The power cord leads are directly soldered to SMD pads on the PCB.

### Firmware
The ESP32 of the Sense PS can be programmed with the firmware of the manufacturer of the sensor [available here](https://github.com/BeFlE/SoMoSe). The firmware facilitates the following MQTT topics:

**Published topics**

Topic | Values | Notes
:----------------------------- |:------------------------|:--------------------------------------------------
somose_name/1/Humidity | number (0...255) | raw value of the sensor
somose_name/1/Humidity-Average | number (0...255) | smoothed, average value of the sensor
somose_name/1/Name | string | name of the sensor
somose_name/1/Temperature | number | temperature of the sensor in degree celsius

For details on the MQTT topics see website of the sensor manufacturer. Be sure to have the ESP32 programmed before potting ;)
After programming, the device is capable for OTA updates via its web interface.

### ESPhome
For direct integration into Home Assistant, ESPhome configuration files also can be downloaded from the sensor [manufacturer site](https://github.com/BeFlE/SoMoSe).

### Mechanics
All components are soldered to the PCB and mounted into the housing. The whole circuit is potted with 2 components resin to ensure outdoor capability.
If someone is interested in a complete device including all parts (PCBA, ESP32, housing, etc.) you can contact me under [email protected].
