YZC-161B Load Cell Sensor Features Load cells are electronic sensors used for measuring weight and force. Load cells are made of alloy and a number of tensile strengths. When force is on the load cell, the spring element is slightly deformed, and unless overloaded, always returns to its original shape. The capacity of a load cell is the maximum amount of force it can withstand. Notes To measure tensile strength changes, we use the HX711 module. It is a high-precision analog-to-digital converter...

YF-S201 Water Flow Sensor Features YF-S201 is a sensor used to measure the water flow. This water flow sensor mainly consists of a plastic valve body, rotor assembly, and a hall effect sensor. This module works based on the hall magnetic effect. So when the water flows through the rotor assembly, the rotor will rotate and the hall effect sensor will produce an electric pulse. By counting these generated pulses, the amount of water passing through the sensor can be calculated.The measuring range of wat...

AP3216 Sensor Features The AP3216C is an integrated ALS & PS module that includes a digital ambient light sensor [ALS], a proximity sensor [PS], and an IR LED in a single package. This module is well suited to applications under clear glass or darkened glass. The proximity function is targeted specifically towards near field application and detects external object with simple configurable zone controlled by registers.  Note You need a 220 to 470 ohm resistor to interface this module. ...

Grove Touch Sensor Features This sensor uses TTP223-B IC. When your finger approaches this sensor, the capacitance of the metal surface will change. So you don’t need to touch sensor completely. Besides, you can put this sensor under a non-metallic surface and touch it. This sensor is waterproof, and it has a variety of applications.  Note There are two red and black wire that have been connected to this sensor. If you want to increase the fingerprint sensitivity, you can remove the black w...

E18-D80NK Infrared Obstacle Avoidance Sensor Features The E18-D80NK sensor is used to detect obstacles and objects. This sensor works based on transmitting infrared rays. First, the transmitter sends the rays in a direct path. This ray hits the obstacle and returns to the receiver. There is a potentiometer on this module that can be adjusted to change this detection distance from 3 to 80cm. In fact, with this sensor, the obstacle can be detected, but the distance cannot be calculated directly. There is also...

4-bit Button Touch Proximity Sensor Features This module has 4 fingerprint touch inputs and 4 digital output pins. It also has 5 LEDs. One for power supply and 4 LEDs indicate fingerprint sensors. If you touch each sensor, the output becomes HIGH and the LED turns on. If you don’t touch, the output will be LOW and the LED turns off.This module can be used on glass, ceramic, plastic and other surfaces. 4-bit Button Touch Proximity Sensor Pinout This module has 6 pi...
