Which IC is used to interface temperature sensor to 8051?
LM35 sensor produces voltage corresponding to temperature. This voltage is converted to digital (0 to 256) by ADC0804 and it is fed to 8051 microcontroller. 8051 microcontroller converts this digital value into temperature in degree Celsius.
How does MLX90614 infrared temperature sensor work?
The working principle of infrared sensor MLX90614 is to transform the infrared radiation signal collected from objects and bodies into electrical signals, send the electrical signal into converter after noise amplification processing by amplifier, then the electrical signal is converted to digital signals and store the …
How do I use MLX90614?
Arduino Wiring
- Connect GND to common power/data ground.
- Connect PWR to the power supply, for the 3V sensor this is about 3.3V. For the 5V version, use about 5VDC.
- Connect the SDA pin to the I2C data SDA pin on your Arduino.
- Connect the SCL pin to the I2C clock SCL pin on your Arduino.
What ADC is used to interface the LM35 sensor with 8051 microcontroller?
The Only method to interface the LM35 with the 8051 microcontroller is by using the internal ADC of 8051.
How do you use an interface temp sensor?
Step 1 – Connect one end of the PT100-S temperature sensor to the analog pin on Arduino. Step 2 – Now, we need to connect the same end of the sensor to 5V on Arduino through a resistor. The value of R2 should be low enough to avoid a low signal to noise ratio.
What are the types of sensors used for interfacing in 8051?
PIR sensors are widely used in motion detecting devices. This article is about interfacing a PIR sensor to 8051 microcontroller. A practical intruder alarm system using PIR sensor and 8051 microcontroller is also included at the end of this article.
Is MLX90614 digital or analog?
The MLX90614 is an infrared thermometer for non-contact temperature measurements. The thermometer comes factory calibrated with a digital SMBus output giving full access to the measured temperature in the complete temperature range(s) with a resolution of 0.02°C.
How accurate is MLX90614?
The MLX90614 offers a standard accuracy of ±0.5ºC around room temperatures. A special version for medical applications exists offering an accuracy of ±0.1ºC in a limited temperature range around the human body temperature.
What is the output of MLX90614?
The MLX90614 provides two methods of output: PWM and SMBus (i.e. TWI, I2C). Both these outputs are easy and simple to use with Arduino, Raspberry Pi and other micro controllers. The 10-bit PWM output provides a resolution of 0.14°C, while the TWI interface has a resolution of 0.02°C.
