Humidity and temperature measurements with Sensirion’s SHT1x/SHT7x sensors using PIC18F2550 (Part 2)

In Part 1 of this tutorial, we discussed about Sensirion’s 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 humidity and provide outputs in fully-cali ...

Humidity and temperature measurements with Sensirion’s SHT1x/SHT7x sensors using PIC18F2550 (Part 1)

Temperature and relative humidity are two very important ambient parameters that are directly related to human comfort. Sometimes, you may be able to bear higher temperatures, if there is a lower relative humidity, such as in hot and dry desert-like environment. However, being in a humid place with not very high temperature may make you feel like melting. This is because if there is high relative humidity, ...

Daft Punk Table Replica Graphics Controller using PIC18f2550

Daft Punk Table Replica Graphics Controller This instructable presents a graphics controller card for something like the Daft Punk Table Replica. This should be used in conjunction with a driver board (output expander) like this one, which will drive the high loads presented by the table. This is a work in progress and collaborations on this instructable are welcome. *audio used under creative commons licen ...

PIC18F2550 : Blink LED using XC8 Compiler

Welcome to another chapter of PIC18F programming Tutorial. In this chapter we are going to program a simple 28 pin PIC18F2550 microcontroller using mplabx IDE and XC8 Compiler. The concepts for programming a pic18f2550 microcontroller is still going to be almost same as previous tutorials on pic18f4550 microcontroller, however since pic18f2550 is a different microcontroller in the same pic18F family, so lit ...

USB Indoor/Outdoor Thermometer using PIC18F2550 microcontroller

USB Indoor/Outdoor Thermometer (or, 'My first USB device') This is a simple design that demonstrates the USB peripheral on the PIC 18Fs. There are a bunch of examples for the 18F4550 40 pin chips online, this design demonstrates the smaller 18F2550 28 pin version. The PCB uses surface mount parts, but all components are available in through hole versions. I use surface mount parts because its faster to make ...
