Description
Shelly Plus Add-on-Kit 4
- Can be used with up to five DS18B20 sensors or one DHT22 sensor. This kitted version comes with 2 x DS18B20 and for a limited time we give in a 3rd Temperature at no cost
- Has an analog and a digital input
- DS18B20 – Temperature sensor (up to 5); please choose the product variant with or without (default variant ships without it)
- DHT22 sensor- if you want to monitor temperature and humidity
Highly compatible
Shelly Plus Add-on-Kit 4 is compatible with most Arduino sensors! Use its digital or analog inputs to measure your desired parameters and create complex automation scenes based on the sensor data.
Irrigation only when needed
Having a beautiful garden is not an easy task and automating your irrigation system can save you time and optimize your costs. Together with a soil moisture sensor, Shelly Plus Add-on can trigger Shelly Plus 1 to turn on the irrigation only when necessary, always skipping the rainy days.
