Overview Lm35 temperature sensor price in bd

The analog signal from the LM35 temperature sensor is proportional to the current temperature. The output voltage may simply be converted to Celsius in order to get a reading on the temperature of the device. Because it doesn’t require any external calibration, the lm35 has an advantage over the thermistor. Additionally, the covering prevents the surface from overheating. Students, hobbyists, and DIY circuit makers love it since it’s inexpensive and accurate. LM35 is utilized in many low-end goods because of its low cost and high precision. Even though the sensor has been around for more than a decade, it is still being used in various products. Robofablab offers a low-cost LM35 Temperature Sensor price in bd.

Features of the LM35 Temperature sensor.

  • Directly calibrated in Celsius (Centigrade).
  • A Scale Factor of • Linear + 10-mV/°C.
  • At 25°C, the accuracy of 0.5°C is guaranteed.
  • Designed to withstand temperatures ranging from -55°C to 150°C.
  • Remote Applications are supported.
  • Suitable for use between 4 and 30 V.
  • A current drain of less than 60 nA is required.
  • It has a low self-heating temperature of about 0.08 degrees Celsius in still air.
  • Non-Linearity is often only 14°C.
  • For a load of 1 mA, the output has a low impedance of 0.1.

How to use the LM35 temperature sensor to figure out the temperature.

  • Build the circuit.
  • Vcc and GND should be connected to +5-20 volts, respectively, for LM35 operation.
  • Make sure that Vout is plugged into the analog-to-digital converter.
  • Take a sample of the ADC’s output voltage, vout.
  • Temperature can be expressed as a voltage.
