What is the purpose of the VCC pin in the LM35 sensor?
LM35 has three pinouts which are: PIN 1: Vcc, it used as input at this pin we apply +5 V input voltage. PIN 2: At this pin, we get output voltage. PIN 3: This pin is used for ground.
Which 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 many pins does LM35 temperature sensor have?
LM35 Sensor Pinout Configuration
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | Vcc | Input voltage is +5V for typical applications |
| 2 | Analog Out | There will be increase in 10mV for raise of every 1°C. Can range from -1V(-55°C) to 6V(150°C) |
| 3 | Ground | Connected to ground of circuit |
How many pins does LM35 IC have?
Pinout Details. As you can see in the above figure, the LM35 IC consists of three pins out of which two are for powering the sensor and the other one is the output signal pin. The sensor can work anywhere from -55 to 150 degrees Celsius.
How do I calibrate my LM35 temperature sensor?
The LM35 device does not require any external calibration or trimming to provide typical accuracies of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C temperature range.
Which IC is used to interface temperature sensor with 8051?
LM35 Temperature Sensor: It outputs 10mV for each degree of Celsius temperature. 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.
How do I set up my LM35?
The LM35 is easy to use; just connect the left pin to power (4V to 30V) and the right pin to ground (assuming the flat side of the sensor is facing you). Then the middle pin will have an analog voltage that is directly proportional (linear) to the temperature in °C.
What is the function of CS pin in ADC0804?
Individual ADC0804 pins functions are explained below. PIN-1 – CS (chip select) Make this pin ground(0) low to active the ADC0804. PIN-2 – RD (Read) Make this pin high(1) and after some time low(0). This will bring data from internal registers to the output pins after conversion (analog to digital converted value).
What are pins of ADC?
The ADC turns the analog voltage into a digital value. The function that you use to obtain the value of an analog signal is analogRead(pin). This function converts the value of the voltage on an analog input pin and returns a digital value from 0 to 1023, relative to the reference value.
How many pins are present in LDR sensor?
3 pins
LDR sensor provide analog output depending on the amount of light in the environment in which sensor is located. LDR sensor basically contains 3 pins for analog input which is GND, VCC, SIG. LDR sensors are used to detect amount of light.
