Shelly The Pill WiFi/Bluetooth Universal SensorShelly The Pill is a compact module designed to work with sensors and automation systems. The device allows you to monitor temperature, humidity, voltage, and digital states, and thanks to its peripheral modes, it works with analog and digital sensors. Powered by USB-C, it can operate continuously in technical and home installations. Its small size and dual 2.4 GHz WiFi and Bluetooth BLE 4.2 connectivity allow for easy integration even in spaces with limited room.Temperature and humidity monitoringThe device works in plug-and-play mode with popular DS18B20 temperature sensors and DHT22 temperature and humidity sensors. It supports up to five DS18B20 probes simultaneously, allowing you to monitor several measurement points at the same time. It is suitable for temperature control in swimming pools, aquariums, water tanks, and technical systems.Extensive configuration optionsThe model is based on the ESP32-C3 microcontroller (8 MB Flash) and offers features characteristic of the Shelly Gen3 platform. It allows you to create schedules, use webhooks, support MQTT, encrypt communication, and create your own scripts. Integration with external systems is possible via MQTT, WebSocket, or HTTP, allowing for easy integration of the device into complex automation systems.Various operating modesShelly The Pill offers configurable operating modes for digital inputs and outputs as well as analog measurement. The inputs and outputs operate at 3.3 V, and the digital mode can be set independently as an input or output. The analog voltmeter built into the device measures voltages in the range of 0-2.5 V, while an external expansion module allows measurements up to 30 V DC. This allows the device to work with door sensors, motion sensors, flood sensors, and other simple digital sensors.Extensions and DC load controlThe functionality can be expanded with the available add-ons. The external SSR module enables two-channel control of low DC load devices up to 30 V / 300 mA, such as LED indicators, small fans, or solenoid valves. The 0–30 V analog module allows you to monitor voltages in 3.7 V, 12 V, or 24 V battery systems.Compact design and USB-C power supplyThe 26 × 19.95 × 8.5 mm housing and a weight of only 3 g allow the device to be mounted virtually anywhere. Power is supplied via a USB-C port with 5 V voltage, and power consumption does not exceed 1 W. This allows The Pill to work in low-voltage installations and systems based on USB power supplies.Included sensor USB-C cable Manufacturer Shelly Product name Pill Color white Dimensions 26 × 19.95 × 8.5 mm Weight 3 g Housing material plastic Operating temperature -20°C to 40°C Humidity 30% – 70% RH Power supply 5 V DC (via USB Type-C port) Power consumption < 1 W Low threshold 2.48 V Maximum digital input voltage 3.3 V Maximum switching voltage 3.3 V Maximum switching current 20 mA DC voltmeter (built-in) 0–2.5 V DC voltmeter (with external addition) 0–30 V Voltage measurement accuracy ±(2% + 5 digits) Supported external sensors 1 × DHT22up to 5 × DS18B20 WiFi connectivity 802.11 b/g/n 2401–2483 MHz Maximum WiFi transmission power < 20 dBm WiFi range up to 30 m indoors and up to 50 m outdoors (depending on conditions) Bluetooth connectivity BLE 4.2 2402–2480 MHz Maximum Bluetooth transmission power < 10 dBm Range up to 10 m indoors and up to 30 m outdoors (depending on conditions) Processor Shelly ESP32-C3 (ESP-Shelly-C38F) Flash memory 8 MB
