An environmental sensor combined with a powerful computing unit

Exo Sense Pi is a compact wall-mounted device that combines a wide set of environmental sensors with the power of the Raspberry Pi Compute Module 4. It integrates temperature, humidity, air quality, light, and motion sensors, plus digital inputs and an open-collector output, making it an ideal solution for monitoring, room management, access control, indoor tracking, and even voice interaction.

The module provides advanced connectivity through Wi-Fi, Bluetooth 5.0, BLE, and an RS-485 bus, with support for standard protocols such as Modbus, I2C, 1-Wire, and Wiegand. With up to 8GB RAM and 32GB eMMC storage, Exo Sense Pi ensures reliable performance and is fully compliant with CE, FCC, and IC standards for both residential and industrial environments.
