Description
An environmental sensor and a powerful server
Exo Sense Pi is a multi-sensor module with a Raspberry Pi 4 computing core and a wide range of connectivity options. Ready for residential and commercial applications such as environmental monitoring and data gathering, BLE positioning, indoor people and assets tracking, rooms management and access control, voice control and much more.
Its broad range of sensors, two digital inputs and open-collector output are routed to a Raspberry Pi Compute Module 4, all in a small wall-mount package.
The Raspberry Pi Compute Module 4 incorporates a high performance quad-core ARM Cortex-A72 processor, Wi-Fi, Bluetooth 5.0 and Bluetooth Low Energy (BLE) wireless interfaces, up to 8GB RAM and 32GB eMMC Flash memory.
Moreover, an RS-485 bus and dedicated I/O lines enable Exo Sense Pi to communicate over standard protocols such as Modbus, I2C, 1-Wire and Wiegand.
Exo Sense Pi is compliant with the CE electromagnetic compatibility standard for emissions in residential environments and immunity in industrial environments. It is also compliant with the FCC and IC electromagnetic compatibility standards.
