HTTM Series Capacitive Touch Sensor Features This touch module is available in different series with a variety of backlight colors. It features low price, high efficiency and long lifespan. The sensor part can also be placed on glass and thin plastic.Its output is on trigger mode which works like a switch. That is, when it is touched, its will be HIGH and remains HIGH until the next touch.The input voltage is 2.7 to 6 V and output pin voltage is 3.3 V. You can download t...

TTP223 Capacitive Touch Sensor Features The TTP223 sensor can be used in a wide range of applications such as smartphones and tablets. It can also detect from behind glass and thin surfaces. When a finger touches the sensor, the module output gets HIGH, and immediately switches to LOW if not touched. The operating voltage is 2 to 5.5 V. Its maximum response time is 220 milliseconds. You can download the datsheet of this module here. [wpdm_package id='19196'] TTP223 Capacitive Touch Sensor...

MicroDuino Touch Sensor Features This touch button is a simple digital output sensor. It uses the TTP223 chip to detect capacitance change. This sensor features small size, high sensitivity, long power consumption and long lifespan. When the sensor is touched, its output is LOW, otherwise it is HIGH. You can download the datsheet of this module here. [wpdm_package id='19221'] MicroDuino Touch Sensor Pinout This Module has 4 pins: VCC: Module power supply – 3.3 to 5 V GND: Ground OUT: ...

SR602 PIR Motion Detection Sensor Features PIR or Passive Infra-Red sensors detect motion based on infrared light of ambient heat. PIR sensors are commonly used in security alarms to detect the presence of human. The SR602 sensor is able to detect movement up to a distance of about 3 meters. This sensor has a digital output. When it detects motion, output will be High and it last 2.5 second. After that it returns to LOW. Note You can adjust sensitivity and HIGH time duration usin...

VL53L0X Distance Sensor Features The VL53L0X sensor is a laser rangefinder. First, the sensor sends a laser pulse, and the distance from object to the sensor is estimated by measuring the travel time of the laser pulse. Due to the very high speed of light, this sensor is not used in applications less than a millimeter. This module can measure a maximum distance of 2 meters. The operating voltage is 2.8 to 5 volts and it uses the I2C protocol to communicate with the microcontroller. You can down...

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...
