“…An example of technical implementation involves connecting the Hall sensor directly to the microcontroller outputs and (if necessary) periodically turning it on for measurement. This mode can significantly reduce the load on the power supply [9,10]. The purpose of this solution is to reduce the average current consumption by reducing the active time of the sensor itself.…”

This paper aims to analyze automatic protection and control measures at pump stations in the event of constant accumulation of groundwater and water dripping from the pump, leading to flooding in the pump station engine room. To prevent this, the pumping station's machine room should monitor the level of groundwater and water leaks from the pump and, promptly, automatically remove excess water with a pump. The excess water is collected in special reservoirs. From these, the ERSU series sensor, which is based on a contact electrode controller, does not allow it to constantly monitor the level in the storage tank within the required limits; therefore, as a completely automated system, it is unstable and cannot support the regulatory requirements for preventing it from starting one of its technical operations. The article discusses the positive aspects of technical solutions and experimental work in the DRV5023 IC with MSP430G2131 controller and no more than 2.7 mA consumer, NE555 IC-based timer and pump mode, stable contactless sensor, sensor-based automatic monitoring, and pumping system. The results are given. (12-17 seconds.) Preparation to start the pumping process is also a standard 4.7 V. power supply circuit. The work is based on production experience and is innovative.

“…The longer the sensor inactivity time, the lower the average current consumption of the circuit [10]. The use of microcircuits of the DRV5023 family [12] made it possible to have low current consumption (2.7 mA) of electricity, did not require an additional stabilizer, and also provided a fast turn-on time (35 μs).…”
