This is a combination of LCD PIC, an assembled printed circuit board from ModernDevice.com, a 20X4 LCD with Blue / White backlight and interfacing connector. – The Arduino Processor. Assembled Serial LCD with Blue LCD

Would you like to view the Relative Humidity RH or The Temperature of your Room, This project will enable you to get these values into the PC on the Serial Port or what you may know as the RS232 port. This project is designed by Peter H. Anderson.

Read Humidity and Temperature on PC

A High humidity like 90% is seen after a Rainfall, A low Humidity like 25% means dry days. A humidity of around 50% is healthy, above that Bugs and Fungus trouble. Less that 40% cause skin and breathing irritations. 60% is comfortable for us and  most equipment. High humidity can cause trouble to unprotected electronics.

This device has a serial interface, that means you could use a Serial to USB circuit and even interface with your tablet.

“This is an assembled unit which interfaces with a PC COM port and provides the capability of measuring the relative humidity and temperature using a Sensirion SHT-71 sensor. It includes an assembled printed circuit board, a 12 VDC wall power unit, and a six foot serial cable (DB9) . The unit interfaces with a COM port or similar at 9600 baud. (A USB to RS232 converter may be used).”
