HiLetgo Analog Current Meter Sensor Module AC 0~5A Ammeter Sensor Board Based on TA12-100 for Arduino

Operating Principle -- Ultrasonic hc-sr04 distance measuring transducer sensor, it consists of ultrasonic transmitter, receiver, and control circuit..
HC-SR04 ultrasonic sensor module -- Using IO trigger for at least 10us high level signal, when triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object, the duration of the signal is the time from sending ultrasonic to returning..
Test Distance Formula -- The distance between the unit and the object is calculated by measuring the traveling time of sound and output it as the width of a TTL pulse,hc-sr04 test distance following formula -- L = 1/2 × T × C ( L is the distance, T is the time between the emission and reception, and C is the sonic speed ).
Package Include -- 5 X HC-SR04 Ultrasonic Sensors , 10 X Female-Male Dupont Cables , 10 X Female-Female Dupont Cables , 3 X HC-SR04 Mounting Bracket.

CYCLESPEED Rechargeable Bike Computer Wireless, Waterproof Speedometer Odometer, Digital LCD Backlight Display Bicycle Bicycle Odometer, Cycling Bike Computer Stopwatch for MTB Road Bicycle

...aterproof rating】Designed with waterproof seal ring on the back cover of the wireless bicycle speedometer, the waterproof protection of bike odometer speedometer is strengthened again to offer you the best experience.
【Installation requirements】To install the bicycle odometer, here are the requirements. 1. The distance between sensor and main unit is less than 50cm, main unit can receive signals and work, closer, better. (The computer sometimes would display a fluctuating data for over 50cm distance, it does not effects all data) 2.The distance between magnet and sensor should be about 5 mm, the closer, the better. 3. The magnet faces the back of the sensor’s battery.
【How to measure wheel size】Measure wheel size before you start settings the cycling computer. Set the valve vertically on the surface and mark it. Make one full spin and stop with the valve in the same position as before and mark it to 0. Measure the distance between the two markers and insert the value(mm) in the computer.
