One morning I woke up and wanted to know what the temperature outside was, and instead of running over to Home Depot and picking up a $2.00 glass thermometer, I decided to build my own wireless temperature sensor. At the heart of the board is a PIC12F675 microcontroller in an SO8 package. The right-hand side of the board houses the linear power supply (LP2950), bottom-center is the DS18B20 1-Wire temperature sensor, and out in left-field you can see the Sure TTL Bluetooth Module.

The MCP9700, MCP9700A, MCP9701 and MCP9701A Temperature Sensors from Microchip offer exceptional performance for the low price. Each have different temperature ratings and accuracy parameters. MCP9700, MCP9700A, MCP9701 and MCP9701A sensors are available in different packaging and are very simple to interface with. Vdd, GND and Vout are all that are required. You should check the datasheet to get a better idea of the parameters for the device you decide to use, though keep in mind that the user module listed below will automatically calculate the temperature depending on the device in use.

If you attempt to save power in the house thoroughly, you can not ignore the standby power consumption of appliances. We made a device to measure the power consumption of appliances. Actually, to say the AC power meters measure the 100V AC current is flowing in the power cord over do it. In general, the voltage is measured casually, is difficult to measure the current. To cut off a part of the circuit current flow from a current meter must be connected to it.

The new PIC18F2550 Project Board was designed as the development platform for student projects. The board platform is suitable for developing the microcontroller based instrumentation. Students may build the signal conditioning board, plugs it to PIC project board, develops the code and programs it with loader cable easily.
