The Mynics IR Sensor is a general purpose proximity sensor, which is usually used for obstacle detection. The sensing range is higher than most other modules. The module consists of an IR emitter and IR receiver pair and also an LM 358 comparator IC. The on-board LED indicator helps check the status of the sensor without using any additional hardware. The power consumption of this module is low and gives a digital/analog output.
The Sound Sensor can detect the sound strength of the environment. The main component of the module is a simple microphone and LM393 level convertor chip. The sensor can provide both digital aswell as analog output.
Ultrasonic Sensor HCSR 04
The HC-SR04 ultrasonic ranging sensor is an economical sensor, which provides 2cm to 400cm of non-contact measurement functionality, with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.
Relay Module 5V 8CH
The 5V 8-Channel Relay interface board can control various appliances, and other equipment with large current. It can be controlled directly by Micro-controller (Raspberry Pi, Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) .
Rotary Encoder -360 degrees
The Rotary Encoder Module, is an incremental electro-mechanical device that converts the angular position or motion of a shaft or axle to digital code. The output of incremental encoders provides information about the motion of the shaft, which is typically further processed in processor / controllers into information such as speed, distance, and position.
Servo Tester Module
There are 3 modes to check servos or ESC:
Manual mode: Turn the knob to operate the servo.
Neutral mode: Makes the servo go back to the neutral point.
Automatic “window wiper” mode: Rotates the servo between maximum angles
