Adafruit Temp Sensor

Additionally because the pct2075 allows the address pins to work in three states high low floating you can have 27 pct2075s on the same bus as.

Adafruit temp sensor.

Handy for when you need to measure something far away or in wet conditions. 1782 this i2c digital temperature sensor is one of the more accurate precise we ve ever seen with a typical accuracy of 0 25 c over the sensor s 40 c to 125 c range and precision of 0 0625 deg c. This guide is part of a series of guides that cover the basics of using adafruit io. All in one device.

While the sensor is good up to 125 c the cable is jacketed in pvc so we suggest keeping it under 100 deg c. It will show you how to send temperature and humidity values wirelessly to adafruit io from a dht22 sensor. Its very similar to the lm35 tmp35 celsius output and lm34 tmp34 farenheit output. 165 wide range low power temperature sensor outputs an analog voltage that is proportional to the ambient temperature.

These stats are for the temperature sensor in the adafruit shop the analog devices tmp36 40 to 150c. Because of that there is really only one way to read the temperature value from the sensor and that is plugging the output pin directly into an analog adc input. To use connect pin 1 left to power between 2 7 and 5 5v pin 3 right to ground and pin 2 to analog in on your microcontroller. Resistance temperature detectors rtds are temperature sensors that contain a resistor that changes resistance value as its temperature changes basically a kind of thermistor in this resistance sensor.

The pct2075 by nxp is a pin compatible drop in replacement for a very common i2c temperature sensor the lm75. The adafruit pct2075 temperature sensor is a code compatible drop in replacement for a very common i2c temperature sensor the lm75. 381 this is a pre wired and waterproofed with heat shrink version of the ds18b20 sensor. The reason we went with the 36 instead of the 35 or 34 is that this sensor has a very wide range and doesn t require a negative voltage to read sub.

Compared to the lm75 however the 11 bit adc in the pct2075 provides more precise measurements when compared to the lm75 s 9 bit adc.

Reading the analog temperature data unlike the fsr or photocell sensors we have looked at the tmp36 and friends doesn t act like a resistor.
