Reviews (0)

NETVOX Wireless Capacitive Proximity Sensor - R718VA is a device to detect the status of toilet water, hand sanitizer level, presence or absence of tissue. This device is connected with a non-contact capacitive sensor can be mounted to the exterior of the container, without direct contact with the object to be detected, which may detect the current water level of positions mounted, or the presence or absence of liquid soap or toilet paper; the detected data is transmitted to other devices through the wireless network. It uses the SX1276 wireless communication module.

Example Applications

Flush toilet water level detection
Hand sanitizer level detection
Whether toilet paper presence or absence

Non-contact capacitive sensor device

Model	XKC-Y25-V
Working temperature	-5~100°C
Working humidity	5%~100%
Sensing container (non-metal) wall thickness	≤20mm (glass, plastic, non-absorbent ceramic, acrylic, rubber, etc. or composite materials thereof)

Waterproof level	IP67
Sensitivity	The sensitivity of the non-contact capacitive sensor must be adjusted in the field according to different liquids or objects and the thickness of non-metallic containers.

Sensitivity
The height of the sensed liquid level or the distance between the toilet paper and the sensor is related to the sensitivity of the sensor; the higher the sensitivity, the lower the level of the induced liquid is detected, or the greater distance between the toilet paper and the sensor (up to approximately 2 cm) is detected.
During installation, when the liquid level below the sensor installation position is not detected, the sensitivity can be adjusted to be higher to detect the wanted liquid level height; when there is paper in the sanitary carton that is not detected by the sensor, the sensitivity can be adjusted to be greater.
Note:
1. Avoid metal materials at the probe mounting site so as not to affect the detection.
2. The liquid with higher concentration will appear on the wall which will affect the detection.
When applied to hand sanitizer, in order to avoid the impact of the wall, users should pay attention to the decision of installation location.
