Sensors & Module

It is 6-30V 1-Channel Delay Power Relay Module with Onboard Adjustable Timing Cycle Switches with Digital LED display It is mostly used in Home Automation Delay Timer Control Switch Module Timer Controller. The Module operates at Operating voltage range of 6-30V, also it supports micro USB 5.0V power supply. Output capability: Can control the device within DC 30V 5A or AC 220V 5A. It can be applied to many fields as there is a wide range of application.

This 801S module changes its resistance level once vibration is detected. It can turn into a switch if the vibration is high. According to the datasheet, it is gold-plated and can withstand 60 million shocks. This module is connected in a voltage divider which can be measured through its digital pinout. Its a high sensitivity 801S Vibration Sensor module, which has one digital output pin(D0), When it detects some vibration up to a certain threshold, it can output High or Low level.

You can use this A88 Metal detector non-contact metal induction detection module as a metal detector. When it approaches any metal, it makes a sound.

This is a module specifically designed to detect metal. The module operates by inducing currents in metal objects and responding when it occurs. A nice onboard buzzer signals when it detects something and an onboard potentiometer allow adjustment of sensitivity. The power cables of the Metal detector non-contact metal induction detection module will need soldering on for the module to function, positive to the outside of the module and negative between the potentiometer and an electrolytic capacitor.
