Remote sensing water and rain station

Remote sensing water level stations are mainly used to monitor river channels, reservoirs, surface water levels, and groundwater levels. Monitoring data can be transmitted to the monitoring platform through GPRS/GSM and Beidou satellite SMS.
1. Main functions
1.1 The water level gauge can be selected arbitrarily (float type water level gauge, pressure type water level gauge, ultrasonic water level gauge, radar type water level gauge, bubble type water level gauge, etc. can be selected), using two data transmission mechanisms of incremental control and timed control. The incremental threshold and timed period can be configured arbitrarily.

1.2 If a rain gauge (tipping bucket rain gauge, weighing rain and snow gauge, sonic rain gauge, etc.) is required, it can be added.
1.3 With large capacity FLASH storage, rainfall data can be stored for more than 3 years.
1.4 It has communication methods such as GPRS/SMS and wireless short-range. Support multi center working mode, telemetry station can send data to up to 5 central stations, each center can have two communication channels and backup each other.
1.5 Supports three data communication methods: self reporting, self reporting confirmation, and response. The three communication methods can be mixed for networking.
1.6 Supports three power management modes: power-off, sleep mode, and permanent online.
1.7 Supports remote wake-up and responds to central commands. In the sleep state of the detection station, the center can wake up the terminal at any time to collect data, read self recorded data at any time, or modify monitoring station configuration information.
If necessary, add the Beidou satellite communication method to the course.
