AVT2824 B

Various types of bicycle computers are available on the market. These are very complex devices with many functions. The simplest devices that only allow speed measurement are missing. We fill this gap with the below set.
The principle of Speer Meter operation is based on the counting of wheel revolutions at the right time. The result is shown on the line of LEDs. The system is very easy to assemble. It has been developed on typical elements of the 4000 series. The calibration process consists in taking into account the diameter of the wheel in the device from which the number of revolutions is read.
The system can be supplemented with AVT2827 (Crazy ruler)

The device is especially recommended for cyclists and anyone who wants to measure speed

Selected parameters:

• rotation sensor - reed switch
• possibility of tuning to the diameter of the wheel
• speed reading - a line of 10 LEDs
• display method - 'bars' of LED diodes
• power supply - 5 - 9 Vdc
• in the set a printed circuit board, a set of elements and documentation
