Heart rate measurement indicates the soundness of the human cardiovascular system. This project demonstrates a technique to measure the heart rate by sensing the variationĀ of the blood volume inside a finger artery, which is caused byĀ the pumping action of the heart. It consists of an infrared LED that transmits an IR signal through the fingertip

Here is a simple, versatile project which indicates the level of water and automaticallyĀ controlsĀ it by using PIC Microcontroller. The Water Level Sensing Section senses the level of water in the tank and sends it (wireless) to the Receiver Section. Receiver Section is connected to the Controlling Section, which process the received information and produces visual,

Thermometer can be easily constructed using a PIC Microcontroller and LM35 Temperature Sensor. LM35 series is a low cost and precision Integrated Circuit Temperature Sensor whose output voltage is proportional toĀ Centigrade temperature scale. Thus LM35 has an advantage over other temperature sensorsĀ calibratedĀ in Kelvin as the users donāt require subtraction of large constant voltage to obtain

Easy Pulse mikro is our new educational pulse sensor in a mikroBus form factor. Like our previous Easy Pulse sensors (Easy Pulse and Easy Pulse Plugin), it is also based on the principle of transmittance photoplethysmography (PPG) applied to a fingertip. The sensor consists of a pair of IR LED and photodiode to detect the

In Part 1 of this tutorial, we discussed about Sensirionās SHT1x and SHT7x series of humidity sensors, their interface specifications, the communication protocol used for transferring data in and out of the sensor, and the equations to convert their digital outputs to actual physical quantities. These sensors are capable of measuring temperature along with relative
This is an example USB project showing how to interface an optical mouse sensor (the ADNS-2620) with a standard XP/Vista computer. The TD-USB-01 board with a PIC18F2550 communicates with: the PC: USB 2.0 through a mini-B connector. the mouse sensor board: SPI over 4-wire flatcable. Here are the technical specifications: PC Win XP/Vista interface application

Over the last few months I have prototyped and built a water tank level sensor for my 9000L rain water tank. The design is based entirely on Silicon Chipās PIC-Based Water-Tank Level Meter, but instead of programming PICs, I prototyped using an arduino, and built the final version using PICAXE microcontrollers. The sensor consists of
