Occupancy and Air Sensor
Detect movement and room conditions and connect over WiFi with a passive IR occupancy sensor, barometer, temperature and humidity sensors, and the Microchip ATSAMW25 module. Prototype quickly with RoomSense and MyDevices Cayenne.
RoomSense Occupancy and Air Sensor
Use sensor data to control your home with the RoomSense passive-IR board. Plug it in to any powered USB port and deliver occupancy, temperature, humidity and barometric pressure to your home automation system.
This tiny USB dongle uses a passive IR motion detector, and temperature, humidity and barometric sensors to monitor a room's conditions and occupancy. The Microchip ATSAMW25 provides a SAMD21 Cortex-M0+ MCU and WiFi connectivity. It integrates easily with cloud IoT platforms such as MyDevices Cayenne.
Pre-flashed with the Arduino bootloader, the RoomSense is easily deployable as a home automation device by developers of all skill levels.
- ARM Cortex-M0+ MCU at 48 MHz
- 802.11b/g/n WiFi
- Barometer, humidity and temperature sensors
- Passive IR motion detector
