Product description: Shelly The Pill - universal sensor module - WiFi / Bluetooth
Shelly The Pill is a multifunctional automation and monitoring module equipped with 2.4 GHz WiFi and Bluetooth BLE 4.2 connectivity . It is designed to work with environmental sensors, analog modules, and low-voltage control devices. Thanks to its compact design and USB Type-C power supply, it can be mounted virtually anywhere – in control cabinets, equipment enclosures, aquariums, greenhouses, or technical monitoring systems. The module supports up to five DS18B20 temperature sensors or one DHT22 sensor , enabling real-time temperature and humidity monitoring. Shelly The Pill also offers 3.3V digital inputs and outputs, analog voltage measurement, and integration with external systems via MQTT, HTTP, and WebSocket . The Shelly Gen3 platform supports scheduling, webhooks, encryption, and custom automation scripts.

Shelly The Pill is just 26mm tall and can be used to intelligently control common digital or analog sensors and low-voltage actuators.
