DHT22 Proteus simulation This topic shows how to interface DHT22 (AM2302, RHT03) digital relative humidity and temperature sensor with PIC16F84A microcontroller, and how to simulate this interfacing using Proteus. Note that for the simulation Proteus version should be 8.1 or higher. With these versions there is no need to install Proteus DHT22 library, it is included with the software, so don't waste your t ...

In this blog there are some topics talking about the DHT11 relative humidity and temperature sensor and how to interface it with different types of PIC microcontrollers. The datasheet of the DHT11 sensor shows its characteristics and how it works. Also the following topic shows the DHT11 timing and how to simulate it using Proteus: Interfacing PIC16F877A with DHT11 (RHT01) sensor Proteus simulation This top ...

Hello everybody welcome back . Today I'm gonna tell how you can display temperature with bar graph on Graphic LCD using PIC microcontroller . The project is very simple to understand if you have concept of Graphic LCD .The program in this project is written in C and Assembly level language &  the compiler used to write the C code is mikroC PRO for PIC V. 7.1.0 .You can download complete project (C and A ...

Abstract: This report represents the design and implementation of a skin temperature measurement system. The system aims to measure the skin temperature from a sensor and send it to the PC using a USB cable to display on screen. The data needs to be updated every second. The PIC18F4550 microcontroller has been used in this project to obtain data from the sensor and send it to the PC using USB 2.0 that has b ...

Theory of operation In series thermocouple soldering iron have a thermocouple in series with their heating element and thus only have two connections (actually one more which is electrically connected to the tip for ESD purposes). When a voltage is applied to the two terminals the tip heats, when unpowered the thermocouple voltage can be read. This controller uses a skipped variable puls modulation to keep ...

Researchers at EPFL in Switzerland have found that adding large organic compounds called guanidinium (CH6N3+) into methylammonium lead iodide perovskite solar cells can provide stable power efficiency of 19%, approaching that of silicon cells. The lab of Mohammad Khaja Nazeeruddin at EPFL Valais Wallis, with colleagues at the University of Cordoba and the Helmholtz Institute in Berlin, has discovered that t ...

Under the “Power by Linear” branding it recently created for the product lines it acquired with its purchase of Linear Technology, Analog Devices has added the LT3964, a dual channel, 36V, high efficiency, synchronous, step-down LED driver with internal 40V, 1.6A power switches and an I2C interface that simplifies LED dimming control. The LT3964 operates with a 4V to 36V input range, and features two indepe ...

Bosch Sensortec announces a world first in sensor technology: the BME280 Integrated Environmental Unit combines sensors for pressure, humidity and temperature in a single package. This unique sensor has been developed to support a broad range of emerging high performance applications such as indoor navigation, home automation control, personalized weather stations and innovative sport and fitness applicatio ...

After the simple interfacing of the PIC18F4550 microcontroller with the DS3231 RTC, now let's add the alarms functionality and temperature monitor to our previous project. Interfacing PIC18F4550 with DS3231 project link: Real time clock & calendar with PIC18F4550 and DS3231 As written in the datasheet the DS3231 RTC has a built-in 2 alarm functions and a digital temperature sensor with an accuracy of ±3 ...

Designing a simple and cheap temperature logger. Part 4: The junk in the trunk. Posted on February 3, 2012 I somehow managed to solve the problem of the serial flash memory write block size vs. the erase block size. I just had to write a custom FAT12 filesystem.. As seen before, the Temperature Logger will act like an USB memory stick. There will be at least two files. One with the time stamped temperature ...
