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 ...

Arduino powered temperature sensing RGB LED nightlight using PICaxe

About a year ago I started on a project to make a temperature controlled nightlight. I was inspired by seeing these lovely LED lamps styled as mushrooms growing out of pieces of wood. Those mushrooms were made out of glass, which was somewhat beyond my skills. However I then saw some had used translucent sculpey to make mushroom nightlights on instructables. So with that discovery it seemed like it would be ...

DHT22 (AM2302) Digital Humidity and Temperature Sensor Proteus Simulation

Like the DHT11, the DHT22 is a digital humidity and temperature sensor which has more benefits than DHT11 like: High precision and range. If we want to understand this topic we have to read the DHT22 datasheet and see how this device works and its characteristics. Note that the DHT22 is available only on Proteus version 8.1 or higher, version 8.0 or later will not work therefore you have to update your vers ...

Temperature controlled fan using PIC 16F877A

You might have come across several applications where we need to control a specific device based on analog parameter. This Embedded system works in a similar concept where we are about to control the speed of a DC motor using based on the external temperature. The rise in temperature will result in increase in speed of the motor and vice versa. These type of Temperature controlled fan systems can generally ...
