When the water level in the rice field reaches the set water level, it will notify you with a sound on the portable receiver! Automatic start and stop of the pump is possible!
Due to the significant difference in electrical resistance between water and air, our company offers a wireless water level sensor for rice paddies that detects the weak current flowing between electrodes to identify the liquid level. The post supporting the detection unit also serves as an electrode, and the position setting for liquid level detection is done by moving the detection rod to the desired position and securing it with a pin through a hole in the detection rod. 【Features】 ■ Zero water level detection (supports mid-season drying, which is not possible with other methods) ■ Cable transmission between the detection unit and the main body can reach 20m (nominal length) ■ Applicable for monitoring water levels in underground tanks and drains where radio waves do not reach ■ Generally, radio waves attenuate in proportion to the square of frequency and distance ■ The 315MHz band used for wireless chimes has a frequency that is 1/7 that of the 2.4GHz band * For more details, please download the PDF or feel free to contact us.

Company information
We manufacture waterproof temperature, humidity, and illuminance sensors using battery-powered wireless level switches and wireless modules. The level switch detects either a decrease or increase in water level and turns the power source, such as a pump, on or off. The software Slip21 records measurements. Operating on a PC, Slip21 receives and records multiple sensor outputs from the wireless module. We are considering its use for agricultural management in facility cultivation. Please feel free to contact us if you have any requests.
