Top 6 Best Capacitive Sensor

Special attention After the switch is installed, the sensing distance needs to be adjusted, otherwise, there will be no response when the switch is turned on.There are two friends recently. The reaction product does not work, First note our products are 100 tested before they leave the factory. Solution 1. Turn Switch control sensing distance behind the product 2 .Send us an email and we will send you a new one..

The intelligent non-contact liquid level sensor uses advanced signal processing technology and high-speed signal processing chip to break through the influence of the wall thickness of the container and realize the true non-contact detection of the liquid level in the closed container.. The liquid level sensor probe is installed above and below the outer wall of the container to be tested the high and low positions of the liquid level. The non-metallic container does not need to be opened, and the installation is simple and does not affect the production.. The liquid level of various toxic substances, strong acids, strong alkalis and various liquids in the high-pressure closed container can be detected.. The liquid to be tested is required to be electrically conductive, the contact surface is non-metal, and the pipe is easy to install and can be widely used.. High and low level output If there is induction, the output is high level no induction, the output is low level. Specially designed for non-metallic pipe liquid level detection.

This is the momentary variety of the touch sensor - touch and it turns on, release and it turns off.. Positive and negative can be used as a touch surface,can replace the traditional touch button.. Four M2 screws positioning holes for easy installation.Module can be installed in such as surface plastic, glass of non-metallic materials.. In addition to the thin paper non-metallic covering the surface of the module , as long as the correct location of the touch , you can make hidden in the walls, desktops and other parts of buttons.. The module is based on a touch-sensing IC TTP223B capacitive touch switch module. In the normal state, the module output low, low power consumption When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode..
