This is the NEXTION HMI a Human Machine Interface device that provides a GUI control of instruments that feeds from your microcontroller. The Nextion is simplified interface to visualize the process between a human and machine, these device is useful
The BMP180 a successor of BMP085 a new generation of high precision, ultra-low power digital pressure sensor. The BMP180 is optimized for use in mobile devices, PDA, GPS navigation and outdoor equipment with a low altitude noise of merely 0.25m
The BH1750 IC is a digital Ambient light sensor IC that drives on i2c / IIC bus interface. It is possible to detect wide range at high resolution rated to 1 – 65535 LUX. Mostly used in Mobile Phone, LCD
This is the Line Tracking Sensor designed for line following robots. The board has two main components IR Transmitter and IR Receiver in one package named TCRT5000. The TCRT5000 are reflective sensors which include an infrared emitter and photo-transistor in
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
