AM307 is a compact indoor ambience monitoring sensor for measurement of temperature, humidity, light, CO2 concentration, TVOC, barometric pressure, and motion. The data will be shown on the E-ink screen in real-time, which helps to measure the indoor environment and comfort. The 7 sensors in AM307 can be configured for threshold detection and can trigger text and email alerts whenever these thresholds are being exceeded.
