    Ultimate Motion, Temperature, and Humidity Sensor

    Milesight WS203 is a wireless LoRaWAN environmental monitoring sensor detecting the motion of humans or animals, surroundings temperature and humidity. It ensures the indoor environment at a preset comfort level via pairing with the HVAC system if motions are being detected, which is a huge energy saver and brings much comfort.

    Sensitive Motion Detection

    WS203 can detect motions of humans or animals Sensitively at wide coverage up to 120° horizontal and 100° vertical within 6 meters based on passive infrared (PIR).

    Adjustable Detection Angles

    The detection range of the PIR sensor in WS203 could be adjusted via different standard PIR covers to adapt to various detection environments.

    High-Precision Temperature and Humidity Detection

    Built-in high-precision TH sensor ensures accurate monitoring of temperature and humidity in the air, detecting changes in real time.

    • Range: -20°C ~ +60°C
    • Accuracy: ±0.2°C
    • Resolution: 0.1°C
    • Range: 0% ~ 100% RH
    • Accuracy: ±2% RH
    • Resolution: 0.5% RH

    High Data Integrity with Storage and Retransmission

    WS203 can store up to 1,000 sets of historical data records with time stamps. When the connection fails, WS203 will continue to collect and store environment data. Once reconnected, the data collected during that period will be retransmitted to the gateway, thus avoiding data loss.

    Milesight D2D Communication

    Milesight D2D (Device to Device) communication protocol featuring LoRa® enables communication among different Milesight LoRaWAN® node devices without a LoRaWAN® gateway.

    • Lower Latency
    • Less than 1 Second Response Time
    • Secure Transmission
    • Reduce Investment Cost

    Ultra-Low Power Consumption

    Based on the low power consumption LoRaWAN®, WS203 can maintain a long battery life of 5 years with a built-in 4000 mAh ER18505 Li-SOCL2 battery and report at a certain rate.

    LoRaWAN® Based

    • Penetrating Signals: data transmission range up to 2 km in urban areas and 15 km in rural areas
    • High Compatibility: compliant with standard LoRaWAN® gateways and network servers
