With its 3.5mm jack connector and 1m length, it provides an easy-to-use, plug n' play temperature sensor option for projects monitoring air or water temperature - from aquariums to servers to warehouse temperature monitoring - and everything in-between!
Plug it into The Pill by Shelly (via the Pill's included Micro-USB to 3.5mm adapter cable) to measure air or liquid temperature in real time, providing stable readings and able to be paired with multiple sensors (via optional splitter accessory) for complete environmental monitoring.
The Pill by Shelly not included
Water Temperature Monitoring
Monitor aquariums, pools, boilers, water tanks, or other liquids with precise temperature readings. The Pill by Shelly connects to your water temperature sensors and sends real-time data to the Shelly Smart Control app. or your favourite home automation system, such as Home Assistant.
Use it to automate heating systems - when the temperature drops, you can trigger pumps or heaters to maintain optimal conditions. Ideal for stabilising aquatic ecosystems, keeping pool water comfortable, and improving energy efficiency.
Air & Greenhouse Climate Monitoring
Whether you're maintaining a healthy indoor environment or creating optimal conditions for plant growth, The Pill by Shelly delivers accurate temperature data using the sensor. Real-time measurements in the Shelly Smart Control app help you automate HVAC systems, thermostats, humidifiers, or greenhouse ventilation. Keep living spaces comfortable and ensure stable conditions for your plants - all with one compact monitoring hub.
Server Room Temperature Monitoring
Use the sensor to keep critical IT equipment safe. Place one or more sensors across racks or hotspots and connect them to The Pill by Shelly. You’ll get real-time readings in the Shelly Smart Control app, allowing you to detect overheating early, automate cooling, and protect servers from costly temperature-related failures.
Food Storage Temperature Monitoring
Cold rooms and food storage areas require strict temperature control. By installing the sensor inside refrigerators, freezers, or storage units, The Pill by Shelly delivers accurate live data to your Shelly Smart Control app. You can track stability, receive alerts if values exceed safe limits, and help maintain compliance with food safety standards.
Warehouse Temperature Monitoring
Warehouses often have temperature variations across different sections. With the sensor connected to The Pill by Shelly, you can monitor multiple zones and view readings remotely. This helps protect heat-sensitive goods, maintain stable climate conditions, and automate heating or ventilation based on real-time temperature data.
