Your cart is empty. The LM35 series are precision integrated-circuit temperature sensors, with an output voltage linearly proportional to the Centigrade temperature. Thus the LM35 has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling.
The LM35 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. The low output impedance, linear output, and precise inherent calibration of the LM35 make interfacing to readout or control circuitry especially easy.
The device is used with single power supplies, or with plus and minus supplies. As the LM35 draws only 60 µA from the supply, it has very low self-heating of less than 0.1°C in still air.

I spent hours trying to figure out what was wrong with my circuit/ software. Finally decided it had to be the IC's. Went to the local electronics store and bought a LM35DZ from them. Installed it and everything suddenly worked. ALL 5 of the IC's I bought from these guys are bad. Total waste of money.

Review for: Bridgold 5pcs LM35DZ LM35 Analogue Precision Centigrade Temperature Sensor IC,To-92Brand: BridgoldNot sure what they are but I checked and re-checked for proper connection when testing these using a 'scope for measurement. Not a one works.Should have read negative the reviews first. I see that some received a working (4 reviews) device but many others did not (11 reviews). I was not in the lucky group.Returning. Zero stars.

This product does not work as advertised. Used it for a school project and it does not read temp like an actual lm35. Voltage is all over the place. Every one in package gave different readings. Used a true sensor from school and everything worked fine. DO NOT BUY

having issues with the temp reading accurately with a +5 degree, as well as the fact that when a heat source is applied the temperature decreases and cold temperature increases.

The LM35 connection is the same as the TMP36; only mind the final calculation.(1) Connection: Place the LM35 on the breadboard with the lettered side facing the Arduino board, and the rounded side facing away. Connect the left pin of the lettered side to 5Volts, the middle pin to an analog pin, and the right pin to GND. (Make sure that there are no flaky connections.)(2) Calculate Temperature with LM35: Sensor value times 5 divided by 1024 returns results in Volts.As per LM35 spec., 10mV is 1 Celsius so x mVolts = x mVolts divided by 10. So everything put together results in: float temperature = sensorVal * 0.48828125

Every single sensor read out at -27 degrees Celsius in a 21-degree room. I spent hours double-checking my wiring and coding thinking that something had to be wrong. I tried all 5 and they were all defective.Don't buy your Arduino equipment on Amazon—their quality isn't as reliable as Adafruit or other businesses that are made by engineers.
