This sensor is very easy to use and having very good accuracy compared to other sensors. The B3603 is an affordable constant current or constant voltage DC to DC converter. Enclosures, Racks & Cabinets. arduino arduino nano communication control system current dc motor digimesh diode diy lab equipment fan gadgets instrument lab lab. void setup() {// initialize serial communication at 9600 bits per second: Serial. When motor turns on and with a very slow speed the pules are not constants, seems the arduino don have speed enought to get the pules in right time (or the connection between the pc and arduino). This project gives quick intro to-1) Using Interrupts of arduino boards (here arduino Due) 2) Interfacing Hall effect sensor of fan 3) Interfacing and displaying real time information on LCD display (here 16 x 2). It uses LM35 as temperature sensor and DC motor as a fan as a. Introduction. Re: Reading fan rpm with microcontroller « Reply #14 on: March 28, 2015, 12:53:04 pm » The fan RPM signal is SLOW, just grabed a laptop fan, on full blast they put out around 130-140Hz, so even using 10 PCINT's the microcontroller has plenty of time to read all that. Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor.
