Irrigation system based on Tasmota
Tasmota can be a very good base for own projects. It has support for a lot of sensors, has a nice easy WebUI, handles WiFi and MQTT and, as this writing, comes with Bluetooth support and Berry as programming language on ESP32 boards.
So why not try to build a plant watering system with it, that does not need a water tap or external electricity?
This is what it should have
- WebUI to control watering timers and the number of seconds a pump should run
- Use SR04 ultrasonic distance sensor to stop pumps when water container is empty so that there will be no damage to the pumps
- Use MI Flora sensors to check if watering is necessary at all
is installed in a garden that has no electricity or town water.
- It runs on a 30W solar panel with a cheap solar charger and a 20AH 12V battery
- It has a 300 l water container that I fill from ground water (using an extra 230V pump)
- It has 2 12V submerged pumps that water a tomato house and vegetable patch
- It uses 2 Mi Flora sensors to check if watering is necessary
- Is connected via WiFi and MQTT to my home
Please have a look at the Wiki for instructions to setup.
Picture will follow.
