Main chip: LM393 Working voltage: for DC 5V Single-channel signal output Low-level output signal used for human body touch sensor alarm Adjustable sensitivity Pin Connector to board: 4 Pins
Operating Voltage: 3.3V-5V Features wide range voltage comparator LM393 Adjustable sensitivity Signal output indicator with the retaining bolt hole, convenient installation Output form digital switch output (0 and 1 high and low level) The output effective signal is low level When there is sound, outputs low level and the signal light
The use of plug-in full-color LED. RGB trichromatic limiting resistor to prevent burnout. Through the PWM adjusting, three primary colors can be mixed to obtain different colors. With a variety of single-chip interface. The working voltage: 5V. LED drive mode: common cathode driver
For beginners who are interested in Arduino A complete set of Arduino’s most common and useful electronic components Infrared sensor receiving module Laser sensor module Temperature and humidity sensor module Infrared sensor module 5v relay module Obstacle avoidance sensor module.
A Color-Coded Cable, with a standard male header connectors. Plug it straight into an Arduino or a Breadboard. No soldering is required. The Pulse Sensor has 3 holes around the outside edge which make it easy to sew it into almost anything. Visualization software (made in Processing) to instantly see the output of the sensor and for troubleshooting.
