    LoRa Low power wireless meter reading module

    Product ID: HAC-ML
    Communication mode: lora

    The HAC-ML system is compatible with water, electricity,gas and heat meter,which is convenient to increase or reduce device and flexible for system expansion.The neighboring community can share one concentrator,to extend the wireless transmission distance without adopting repeater,greatly reduce the system cost and improve the success rate of meter reading.

    The four-meter centralized reading system, can effectively solve the problem of water, electricity, gas and heat data collection, which contributes to the integrated management of water, electricity, gas and heat,provides convenience and quality service for residents, helps utilities reduce costs and provides security for the construction of smart cities.

    1)Functions obtain metering,protection against electromagnetic interference,voltage detection,power-off storage,valve in-position switch status detection,valve control circuit and automatic dredging valve etc.

    2)Support sensor measurement of reed switch,hall,nonmagnetic and photoelectric direct reading (customized),etc.
    3)Utilizing TDMA to synchronize the communication time unit automatically and avoid data collision thoroughly
    4)Utilizing frequency hopping technology to avoid adjacent or co-channel interference.
    5)Actively bubble data once every 24 hours
    6)Support three working mode:
    LOP1 (Wake-up in real time remotely,response time:12s,the battery life is more than 8 years)

    LOP2(The max response time for closing valve is 24hours,the response time for opening valve is 12s,the battery life is more than 10 years)

    LOP3(The max response time for valve open/closed is 24 hours,the battery life is more than 12 years)

    Working mode can be switched automatically by concentrator in its application.The standard spring antenna for automatic dredging valve is available.It can also be customized for users a variety of flexible circuit board antenna or other metal antenna.

    7)Optional soldering Farad capacitor or SPC1520 battery capacitor,or matched capacitor soldered by clients.

    8) Equipped with 3.6Ah capacity type ER18505 lithium battery ,1 Farad capacitor, 6 cores waterproof metering cable and spring antenna

    9) Working temperature range
    Wireless acquisition module:-30℃ ~80℃
    SPC1520 capacitor:-30℃ ~75℃
    Battery and Farad capacitor:-25℃ ~65℃

    10)Dimension:42.1mm*24.8mm*3.2mm
