The MSR-1 CO2 is a millimetric presence sensor coupled with a CO2, UV, LUX, temperature, humidity and pressure sensor. Based on ESPHome, it is designed for Home Assisant users.
The MSR-1 integrates a wide range of sensors into a compact and affordable housing. With dimensions of 40.5mm by 32mm and a profile of just 13.2mm, this sensor fits seamlessly into any space.
mmWave Radar Sensor (HLK-ld2410b): Recognizes the most subtle movements. Ideal for instantly detecting when someone enters a room and keeping you informed of their presence, even with minimal movements. Leave lights or fans on in a room until everyone has left.
LUX and UV Sensor (LTR-390UV): Offers more accurate and higher-quality light readings thanks to a dedicated light sensor placed in an optimal location. Check the UV index or simply the light level (lux).
CO2 Sensor: This optional add-on adds a CO2 sensor to the set, which comes pre-calibrated and ready to use. Manage thermostat or fan commands based on room conditions or receive an alert when CO2 levels are high.
Temperature, Humidity, and Pressure Sensor (BME280): Provides accurate readings of temperature, humidity, and pressure. Pressure enhances CO2 sensor readings. Note: The ESP32-C3 in constant WiFi connection generates significant heat; you may need to adjust the offset based on your configuration, and temperature/humidity readings will not be as accurate as a dedicated sensor with less heat buildup.
Bluetooth Tracker (ESP32-C3-Mini) - YAML Configuration Required: Track Bluetooth devices in your home, allowing you to know which devices are closest to the sensor. You need to know the MAC addresses of the Bluetooth devices you want to track.
** Mainly Android. Unfortunately, there doesn't seem to be a good way to track iPhones in Home Assistant. Find your phone if you left it in the office or bedroom or detect who just entered the room.
RGB Pixel: Uses color-coded alerts for different home scenarios.
Piezo Buzzer: Emits different types of beeps depending on different alerts.
Exposed GPIO: GPIO pin, 3V, 5V, ground, and I2C exposed on the back of the board. This allows you to solder your own additions.
