Interface single and Dual IR Infrared sensor with PIC18F4550 and LCD

In this another tutorial on sensors  for beginners, we are going to interface single and multiple Infrared IR sensors with Arduino Uno development board, working simultaneously and have the status displayed either on an ( 4X16 LCD ) LCD module (jhd162a) or an LED. We are going to cover three chapters in single tutorial in simple step by step fashion. The purpose of this tutorial is to serve the basics for b ...

LED fireflies prototype using PIC12f683 microcontroller

LED fireflies prototype hello all, heres an attempt i made at something like an LED throwie..the problem (for me) with led throwies is that they just consume their battery, and produce light.. but they could be better at doing both.. first you have to accept the premise that your willing to spend a bit more for the tradeoff.. the inspiration for this came from some of my other projects, and of course the "L ...

4 DIGITS THERMOMETER USING DS18B20 DIGITAL SENSOR

Updated on 17/01/2016 (a and b segments were swapped on drawing) Counter based on PIC16F628A . Included C code and circuit diagram. Displays -55 to 125 centigrade. The temperature is read every 15 seconds, can be changed in the code. The math is using integers to calculate the degrees and the tenths of degrees are calculated separately. The 7 segment LED is common cathode, 4 separate digits can be used with ...

Sensor Technology for Health and Fitness Applications

By Jon Gabay Contributed By Electronic Products 2015-10-28 Determining the state of our health has always been a matter of finding a way to monitor and measure the body’s most basic functions. Before instrumentation, visual indicators were used that allowed us to know, for example, what our body temperature should be, what a healthy pulse is, and what an acceptable respiration rate is.   Today, with an ...

Humidity sensor using 8051

The communication protocol is explained as follows. The MCU (microcontroller unit) first sends a low signal of width 18mS to the DHT11. After this signal, the MCU pulls up the communication line and waits for the response from DHT11. It make take up to 2. to 40uS. Then the DHT11 pulls down the communication line and keeps it low for 80uS. Then DHT11 pulls up the line and keeps it high for 80uS. Then the DHT ...

Maxim bets its shirt on integration

Description The MAX31865 is an easy-to-use resistance-to-digital converter optimized for platinum resistance temperature detectors (RTDs). An external resistor sets the sensitivity for the RTD being used and a precision delta-sigma ADC converts the ratio of the RTD resistance to the reference resistance into digital form. The MAX31865's inputs are protected against overvoltage faults as large as ±50V. Progr ...

Combo MEMS sensor solution with integrated gas sensor

The BME680 from Bosch Sensortec is the world’s first environmental sensor combining pressure, humidity, temperature, and indoor air quality in a single 3×3mm2 package. The new IC enables mobile devices and wearables to monitor indoor air quality measurement in a low power, small footprint package. The level of integration is what makes this solution so attractive as well as Bosch’s capabilities with softwar ...
