DEVELOPMENT OF SOLAR HEAT CONCENTRATION BOX DRYER AND LM 35 SENSOR, A TOOL FOR TEMPERATURE MEASURING DEVICE

The solar heat concentration box is a system which convert the solar energy to heat energy in a closed system for farmers to dry their farm produce. The system uses an electronic system which is made up of LM 35 sensor enclosed in the dryer. The LM 35 is interfaced with an Ardiuno MEGA microcontroller. The microcontroller converts the analog signal output generated from the sensor to a digital output signal which is been display on visual system. The analog device will be used to measure the temperature inside the heat concentration box at a particular time or period of the day. The system will enable farmers to dry perishable farm produce which is seasonal. This will reduce food shortage and increase per capital income of farmers during the off-farming season.
