Hall Effect Switch Speed Sensor module (no potentiometer) for Mega2560 which makes the transmitting power

which makes the transmitting power achieves 100mW (20dBm) while the receiving sensitivity enhanced by 10dB

Raspberry pi has been well known as credit card size computer

Connect to ground on MCU

Number of Pins: 6 Pin / 8 Pin / 10 Pin / 5 Pin / 15 Pin

Hall Effect Switch Speed Sensor module (no potentiometer) for Mega2560 which makes the transmitting powerFeatures: When the sensor senses a magnetic field, the digital output is low and the signal light is on; if no magnetic field is sensed, the digital output is high and the signal is not lit. With power indicator and signal indicator. Small volume, high sensitivity, fast response speed, good temperature performance, high accuracy, high reliability. LM393 comparator output, good waveform, strong driving ability. It can be used for motor speed
