Heart beat pulse sensor interfacing with pic microcontroller

Heart Beat rate is most important parameter in monitoring any person’s health. In the modern era of wearable devices, there are lot of devices which can measure heartbeat, blood pressure, footsteps, calories burnt and lot of other things. These devices has pulse sensor inside them to sense the pulse rate. Today, we will also use a pulse sensor with PIC Microcontroller to count heart beat per minute and the ...

Interfacing LM35 temperature sensor with PIC18F4550 microcontroller

Interfacing PIC18F4550 with LM35 This small topic shows the circuit diagram and CCS C code of the interfacing of LM35 temperature sensor with PIC18F4550 microcontroller. The LM35 temperature sensor is three pin device (VCC, OUT and GND) with an output voltage linearly related to Centigrade temperature. Since the LM35 output varies with dependent to the temperature we need ADC (Analog-to-Digital Converter) m ...

BROADCOM AFBR-S50 TOF LASER LIGHT SENSOR MEASURES UP TO 10 METERS

The AFBR – S50 is a multipixel distance and motion measurement sensor. It has an integrated 850nm vertical cavity surface emitting laser (VCSEL) which uses a single voltage supply of 5V. It’s measurement rates are quick and as fast as 3 kHz, which is a distinguishing feature. However, this is not the reason why the AFBR – S50 stands out. It is different because unlike other Time of Flight (ToF) ranging sens ...

Fan Speed Control Is Cool!

Abstract: Temperature-based fan control is a necessity in a growing number of systems, both to reduce system noise and to improve fan reliability. When fan control is augmented by fan-speed monitoring, a speed-control loop can be implemented that is independent of manufacturing variances and wear on the fan. In addition, a fan that is about to fail can be identified so that it can be replaced before it fail ...
