Shelly's PLUS sensor add-on is compatible with Shelly PLUS series relays (Shelly PLUS 1, Shelly PLUS 1PM, Shelly PLUS 2PM) and the PLUS i4 input module and makes smart devices capable of connecting to analog and digital sensors .
Characteristics:
- It has an analog and a digital input
- It can be used with up to five DS18B20 sensors or one DHT22 sensor.
- DS18B20 - Temperature sensor (up to 5),
- DHT22 sensor - if you want to monitor temperature and humidity
WHY SHELLY PLUS SUPPLEMENT?
Measure and control with precision: Shelly Plus Add-on is a galvanically isolated sensor interface for all Shelly Plus relays. Use it to measure temperature and humidity using its 1-wire terminals or connect different analog and digital sensors for complex automation and greater efficiency.
HIGH COMPATIBILITY WITH SENSORS
Highly compatible Shelly Plus Add-on is compatible with most Arduino sensors! Use its digital or analog inputs to measure desired parameters and create complex automation scenes based on sensor data.
USE CASES
Garage Door Position: When paired with a Shelly Plus 1, you can connect a reed switch sensor to the digital sensor of the Shelly Plus Addon and track the status of the garage door. In this way, you will always know if it is open or closed when you are away and you will take the appropriate measures.
Control the heating of the water in the aquarium : Using the Shelly Plus Add-on and two DS18B20 sensors, you can easily measure the precise temperature inside the aquarium, as well as the room temperature. Based on this data, you can maintain a comfortable and healthy environment for your pets. In addition, you can connect a liquid level sensor to the supplement and always make sure that the water level is at the optimal level.
Control your lights based on brightness: together with an LDR (photoresistor), the Shelly Plus Add-on can trigger a Shelly Plus 2PM to open the blinds when the room is too dark and it's still daylight. In addition, when the brightness is low, the Shelly Plus Add-on can trigger a Shelly Plus 1 to turn on the lights at the right time.
Follow the weather: Outdoor motorized awnings and shades offer pleasant shade to your guests on sunny days. However, a strong wind, without exception, can damage them beyond repair. By combining it with a wind sensor connected to the Shelly Plus AddOn, the Shelly Plus 2PM can automatically close the outer canopy to protect them from the wind. In addition, the Shelly Plus Add-on with a rain sensor can trigger the Shelly Plus 2PM to open the awning just in time to protect your guests.
Irrigation only when needed: having a beautiful garden is not an easy task, and automating the irrigation system can save you time and optimize your costs. Together with a soil moisture sensor, the Shelly Plus Add-on can trigger the Shelly Plus 1 to start watering only when needed, always skipping rainy days.
Motion-controlled lights: The Shelly Plus Add-on can also be connected to a PIR sensor to illuminate rooms you use occasionally around the house. In this way, when you enter the room, the light will be on as long as you need it.
