Sfera Labs Exo Sense RP Multi-Sensor Modules

Sfera Labs Exo Sense RP Multi-Sensor Modules are small form factor, low-power edge-computing multi-sensor modules built around the Raspberry Pi RP2040 microcontroller unit (MCU). Ideal for installation in space-constrained, indoor environments, Sfera Labs Exo Sense RP module combines the performance and versatility of the RP2040 MCU with an array of sensors in a wall-mount enclosure measuring 80mm x 80mm. As well as operating as a standalone edge-computing multi-sensor module, a series of RP modules can be deployed as complementary satellite units for complex Exo Sense networks. Exo Sense RP integrates temperature, humidity, air quality (VOC), light and motion sensors, a microphone for noise detection, and advanced audio processing. Additional peripheral and custom sensors can be connected through communication interfaces to extend the sensing capabilities in areas such as CO2 monitoring, seismic monitoring (earthquake detection), and vibration measurement.

The module incorporates general-purpose I/Os (GPIOs) to monitor external signals and control actuators while an RS-485 and other digital interfaces can be used for system integration and communication with other devices, such as Wiegand keypads and card readers. Alerts and status signals can be implemented via an embedded LED indicator and piezoelectric buzzer.
