Sensor module PRO Add-onArt. no.: 9450056
Shelly PRO Sensor Add-on is a galvanically isolated DIN rail accessory that turns compatible Shelly Pro devices into sensor hubs. The module offers two 1-Wire connectors, two analog inputs (0–10 V), two digital inputs (±15 V), and a potential-free solid-state relay output.
Connects via Shelly's internal serial interface and is powered by 12 V from the host device — no separate power supply or external controller is required. Sensor data is directly integrated into the host device's web interface, scripting, MQTT, and automations. Galvanic isolation on all inputs protects sensors and the host device in environments with mixed voltage levels.
Supports DS18B20 (up to five per 1-Wire channel), DHT22, NTC resistors, LDR resistors, PIR sensors, soil moisture sensors, ultrasonic sensors, and other 0–10 V analog sensors. Compatible with most Arduino sensors.
Compatible host devices: Shelly Pro 1, Pro 1PM, Pro 2, Pro 2PM, Pro 3EM, Pro Dimmer 0/1-10V PM, Pro Dimmer 1PM, Pro Dimmer 2PM and Pro EM-50.
Areas of application:
•Monitoring of temperature, humidity and open doors/windows from the electrical control panel
•Optimizing heating, cooling and ventilation with temperature and humidity sensors
•Motion-controlled lighting with PIR sensors in halls, warehouses and offices
•Protection against water leakage with digital water sensors and automatic shutdown
•Smart irrigation with soil moisture sensors for greenhouses and outdoor facilities
•Specialized monitoring projects with Arduino-compatible sensors
