IR Light reflection switch, useful for obstacle avoidance or line following, for obstacle avoidance you can place this module in front of the sender /receive diodes that will cause the out pin to be pulled low at distance of 1cm.
photo interrupter is transmission type photo sensor that integrates optical receiving and transmitting elements in a single package please see the diagram below. Since the method involves light blocking commonly named photo interrupter. A long life infrared photo diodes is
Another illustration that demonstrate how to use the buzzer both passive and active. The difference between an active and passive is. The active buzzer has a built in oscillating source that will make a sound when amplifying a power compare
Linear Sensor are critical to the performance to their sensitivity and linearity over their specified operating temperature range and immune to most environmental disturbance that may affect optical or mechanical devices, such as vibration, moisture, dirt or oil films, ambient,
The DS18B20 is a digital thermometer provides 9bit to 12bit Celsius temperature measurement, this device has an alarm function with nonvolatile that user can program upper and lower trigger points. DS18B20 communicates over one wire bus or one data line
In this illustration we will going to wire the light interrupter. A photo interrupter is transmission type photo sensor that integrates optical receiving and transmitting elements in a single package please see the diagram below. Since the method involves light
