DS18B20 communication is using 1 wire port. With the 1wire port the memory and control functions will not be available before the ROM function protocol has been established. The master must first provide on of five ROM function command. 1.
IR (Infrared) obstacle avoidance Sensor module uses infrared reflection principle to detect obstacle. This sensor has a high precision components paired of infrared transmitter and receiver. The transmitter tubes emit a certain frequency of infrared when detecting a direction or
Another illustration how to wire and build a simple water level, rainfall, leakage & water overflow detection. As you can see the first diagram below its uses a water sensor module which can be plug easily or build your own
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 MPU6050 on Raspberry Pi. The MPU 6050 sensor board contains a MEMS ACCELEROMETER and MEMS GYRO a single chip that provide a very accurate data, as it contains 16bits analog to digital conversion
Another illustration that demonstrate using rotary encoder. Rotary encoder is an electro mechanical device that convert the angular position or a motion of a shaft or axle to analog or digital code. Rotary encoder are usually used at the side
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
Push buttons are simple switch mechanism for controlling some aspect of a machine or a process. Buttons are typically made out of plastics, metal, carbons or rubber. The surface is usually flat or shaped to accommodate the human finger or
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,
Another illustration how to control and wire the Rolling Ball Tilt Switch or Ball Sensor along with Raspberry Pi. Ball tilt switch allows you to detect an location or inclination they are small and easy to wired-up it use low
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
