PebbleSense Presence Sensors
PebbleSense devices are all based on the same core ESP32 platform and so please refer to the PebbleSense Common Specs for features and specifications that are common across the PebbleSense range HERE. We integrate IoT sensor devices from across the industry and are excited to work with some of the most advanced sensor manufacturers globally.
PebbleSense
Presence Zones
This millimeter-wave presence sensor utilises a wavelength signal of 24GHz. It has a detection range up to 6m and so suitable for small to medium size rooms. It can track speed and direction of three people simultaneously and have up to 4 different detection zones. It is suitable for human presence detection, environmental monitoring, and real-time monitoring deployments where accurate detection, counting and privacy are important.

Presence Health
This Presence Detection Sensor is a high-precision 60GHz millimeter-wave radar sensor engineered for advanced human detection. Unlike standard 24GHz millimeter-wave sensors that are limited to detecting presence, speed, and distance, this sensor offers enhanced detection capabilities, including fall detection and sleep monitoring. Its ability to recognise human postures using a point cloud imaging algorithm allows for the detection of whether someone is lying down and for the precise monitoring of life signs. This sensor can detect motion or even when a person remains static, making it superior to traditional sensors like PIR, which require movement to detect presence.

| Primary Use Cases | Aged & Disability Care |
