Description WS202 PIR & Light Sensor AM103 is a compact indoor ambiance monitoring sensor for the measurement of temperature, humidity and CO2. These data will be shown on the E-ink screen in real-time, which allows quantifying of the indoor environment and comfort. AM103 is widely used for offices, stores, classrooms, hospitals, etc. Apart from screen display, sensor data can also be transmitted using LoRaWAN®. With this low-power technology, AM103 can work for more than 3 years with 2 replaceable batteries. Combining with Milesight LoRaWAN® gateway and Milesight IoT Cloud solution, users can manage all sensor data remotely and visually. Easily to install with the convenient size Built-in light sensor, combine PIR sensor to achieve triggers Ultra-wide-distance wireless transmission up to line of sight of 15 km Equipped with NFC for one touch configuration, support card emulation mode Support Milesight LoRa D2D protocol to enable ultra-low latency and directly control without gateway Function well with standard LoRaWAN® gateways and network servers Compliant with Milesight IoT Cloud Specifications: Wireless Transmission Technology LoRaWAN®, LoRa D2D Frequency CN470/IN865/RU864/EU868/US915/AU915/KR920/AS923 Tx Power 16 dBm (868 MHz)/22 dBm (915 MHz)/19 dBm (470 MHz) Sensitivity -137 dBm @300bps Mode OTAA/ABP Class A Measurement PIR Detection Area 120 ° Horizontal, 100 ° Vertical Detection Distance Maximum 8 m Light Status Bright/Dark (Determine 1-60000 lux as Bright or Dark according to custom threshold) Software Configuration NFC Advanced Feature LoRa D2D Controller Physical Characteristics Power Supply 1 × 1650 mAh ER14335 Li-SOCl2 battery Battery Life* Around 4 years (30 min interval 30 triggers per day) Operating Temperature -30°C to 60°C Relative Humidity ≤90% (non-condensing) Ingress Protection IP30 Dimension 50 × 50 × 23.8 mm (1.97 × 1.97 × 0.94 in) Material Anti-flaming Polycarbonate Color White Installation On the flat surfaces with screws or 3M tapes * Tested under laboratory conditions and for guideline purposes only.
