I am also using at89c51 for interfacing lm35(temperature sensor) and hih 4030(humidity sensor). Sensor is any device capable of sensing physical parameters (like temperature, pressure, proximity, etc) and then convert into electrical signals so that it can be used for processing. LM35 temperature sensor LM35 Temperature Sensor Introduction. LM35 is a 3 pin Using the ADC to get the analog output voltage of the sensor then converting it back to Celsius degrees, and finally display the result on an LCD and also send it via serial port to a host PC to monitor the temperature remotely. Abstract: This application note introduces the user to software for interfacing a DS5000 (8051 compatible) microcontroller to the DS1620 digital temperature sensor. Temperature sensor(lm35) interfacing with 8051. The 8051 considers any voltage between 2 and 5V at its port pin as HIGH and any voltage between 0 to 0.8V as LOW. Various sensors are being used to measure these quantities in analog form. The output of ADC then directly feed to ADC0804 which converts input voltage in 8-bit binary number. All these sensor data is processed and transmitted to the remote mobile via GSM module. LM35 is a well known low cost temperature sensor and is directly calibrated in Degrees Celsius meaning that the output voltage … Interfacing I2C temperature sensor DS1621 with 8051 microcontroller. Temperature Sensor Interfacing with 8051; Temperature Sensor Interfacing with 8051. Software code is provided that reads the DS1620 temperature register and calculates high-resolution results based on data from the counter and slope accumulator registers. admin June 28, … hi i'm interfacing a TC77 thermal sensor which uses a i2c protocol.as i'm new to i2c can any1 guide hw to interface it 8051. i'm uploading the data sheets,code which i hav written & interfacing diagram with 8051.can any one pls go through these data n help me out to read the data from TC77 thermal sensor.
