# strawberry-pi-greenhouse # strawberry-pi-greenhouse
Strawberry Pi Greenhouse is a little project that i made in my holidays. It's a software that sends sensor data (temperature, water level) to a Homeassistants instance and can receive commands from this HA instace to control a relay.
#Installation
To activate the sensors you have to add these lines to you /boot/config.txt file on your raspberry pi micro sd card. You can change the pin numbers if you want.
```
dtparam=i2c1=on dtparam=i2c1=on
dtparam=i2c_arm=on dtparam=i2c_arm=on
enable_uart=0 enable_uart=0
#i2c Temperaturesensor #i2c Temperaturesensor
#dtoverlay=i2c-gpio,bus=2,i2c_gpio_delay_us=1,i2c_gpio_sda=2,i2c_gpio_scl=3 dtoverlay=i2c-gpio,bus=2,i2c_gpio_delay_us=1,i2c_gpio_sda=2,i2c_gpio_scl=3
#i2c Moisturesensor #i2c Moisturesensor
#dtoverlay=i2c-gpio,bus=3,i2c_gpio_delay_us=1,i2c_gpio_auot=4 dtoverlay=i2c-gpio,bus=3,i2c_gpio_delay_us=1,i2c_gpio_auot=4
```
Also you have to enable the i2c devices in the raspi-config menu. If you dont know how to do it you can just google it.
