SW-520D Vibration Tilt Sensor Features The SW-520 sensor consists of two metal balls which switches as a trigger. When the switch is positioned horizontally, and when the sensor angle is less than 10°, the circuit is open (off state) and more than 10°, it is closed (on stated). But when the switch is positioned vertically, the circuit is open when the sensor angle is less than 45°, and close when the angle is more than 45°. To see exactly how this sensor works, read the datasheet. The SW-520D sensor is ...

TMP36 Temperature Sensor Features The TMP36 sensor is used to measure temperature from -40°C to +125°C and its tolerance threshold is +150°C. This sensor is calibrated directly on Celsius and its accuracy is 2°C. This sensor has an analog output. The output voltage changes linearly as the temperature changew. For example, the sensor output voltage is 0.75 volts at 25°C and 2.7 volts at 125°C.This sensor can be used in environmental control systems, thermal protection, fire alarms, CPU thermal m...

LJ12A3-4-Z/BX Inductive Proximity Sensor Features Proximity sensors are used to detect the presence of nearby objects. The LJ12A3-4-Z / BX sensor has three pins, two of which are connected to a supply voltage of 6 to 36 V. The output pin is PNP and NO (Normal Open). That is, it is normally Low and when it detects an object, it becomes HIGH. The detection distance is 4 mm, and it can only detect metal objects such as copper, aluminum, iron, etc. Note Since the operation voltage is more than 5 V,...

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...

TTP223 Capacitive Touch Sensor Features The TTP223 sensor can be used in a variety of applications such as smartphones and tablets. The sensor can recognize objects even from behind glass and thin surfaces. The operating voltage is 2 to 5.5V. The maximum response time is 220 milliseconds. This module has two non-soldered adjustment pins: A and B. The working modes are as follows:A and B both open: The default value of the output pin is LOW. When the sensor is subjected to touch, the output is HIGH, and...
