產品介紹：
SCJ-DATA21 (IP68) low-power measurement and control terminal is an integrated 4G DTU, lithium battery and low-power IoT data acquisition terminal; built-in 12v 22.4AH or 44.8AH lithium battery (larger capacity can be customized), protection level reaches IP68, equipped with low-power Bluetooth to support mobile phone on-site configuration, support flow or water level or other sensor data acquisition, built-in 16MB memory, can meet more than 1 year of data storage needs, while supporting remote configuration upgrade function, reducing the difficulty of customer installation and use.
特徵：
Internally integrated 4G DTU, communication can be achieved without the need for an external DTU:
The protection level reaches IP68 and can work underground for a long time:
Built in lithium battery, integrated design, easy installation:
The low standby power consumption and optimized acquisition and transmission algorithm greatly increase the battery working time:
Built in low-power Bluetooth, convenient for on-site non-contact debugging and setting parameters through mobile phones, and querying data:
Supports USB interface, which can be used to connect with computers for configuration, data query, historical data export and other functions;
Support external charging interface, optional external solar or mains power supply:
Supports 1 485 or 2 4-20mA interfaces:
Support 1-channel pulse/switch signal acquisition (default not enabled)!
Built in external independent watchdog ensures stable and reliable operation of the device;
Support local/remote configuration upgrade, historical data resend function:
Extremely low standby power consumption (<30uA, requiring only 0.26AH battery for 1 year of standby):
Support 3 central stations to send data simultaneously (at the same time, 3 central stations can send data simultaneously):
Support communication between three central stations using different communication protocols:
Support rapid customization of communication protocols and sensor acquisition protocols;
Can be directly matched with various water quality, flow rate, or water level gauges of the company for underground use:
