YwRobot Touch Sensor Module Features Touch Sensor is used to detect human finger touch. It is known as a touch switch as well. These sensors are easy to use and useful in many projects. Before touching the sensor, the output signal is always HIGH. When a human finger touches the sensor, it will generate a LOW level signal. This module also has an LED that lights up when the sensor is touched. Note This module works in trigger mode. That is when the sensor is touched, the digital output is LOW a...

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: ...

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...

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...

Overview In this tutorial, you will learn how to use a soil moisture sensor. Practical examples are also provided to help you master the code. What You Will Learn How soil moisture sensors work How to use soil moisture sensor with Arduino Soil Moisture Sensor - How Does It Work? The soil moisture sensor consists of two probes that measure the volume of water in the soil. The two probes allow the electric current to pass through the soil and, according to its resistance,...

EMG Muscular Signal Sensor Features In medical research, measuring the activity, contraction and expansion of muscles is important. The EMG muscle sensor measures the muscle activity and produces a signal to show the amount of expansion and contraction. Therefore, the output depends on the amount of activity in the selected muscle. 3 Green, red and yellow electrodes connect to the module for transmitting electrical signals from the muscle motion. Features: Small Form Factor Specially Designed for Micr...
