· About DHT11 (RHT01) relative humidity and temperature sensor: The DHT11 sensor comes in a single row 4pin package and operates from 3. 3 to power supply. It can measure temperature from 050 °C with an accuracy of ±2°C and relative humidity ranging from 209 0 % with an accuracy of ±5%. The sensor provides fully calibrated digital outputs for the two measurements.

The gas sensor output voltage is directly given to the PIC18F4550 microcontroller. PIC18F4550 microcontroller can read the analog voltage from any sensor, so we have not used analog to digital converter IC in this project. PIC18F4550 can read 8 analog inputs. Out of these 8 inputs, we have used one analog input pin for the LPG gas sensor.

20160428· The load sensor senses the weight of the gas cylinder and gives the result in kilograms.
