Adafruit Temp Sensor

165 wide range low power temperature sensor outputs an analog voltage that is proportional to the ambient temperature.

Adafruit temp sensor.

Adafruit industries unique fun diy electronics and kits mcp9808 high accuracy i2c temperature sensor breakout board id. Adafruit industries unique fun diy electronics and kits waterproof ds18b20 digital temperature sensor extras id. Any driver that supports the adafruit unified sensor abstraction layer will implement the. 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.

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. Handy for when you need to measure something far away or in wet conditions. 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 industries unique fun diy electronics and kits tmp36 analog temperature sensor tmp36 id.

These stats are for the temperature sensor in the adafruit shop the analog devices tmp36 40 to 150c. 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. Its very similar to the lm35 tmp35 celsius output and lm34 tmp34 farenheit output. 3328 for precision temperature sensing nothing beats a platinum rtd.

The adafruit pct2075 temperature sensor is a code compatible drop in replacement for a very common i2c temperature sensor the lm75. 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. 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. All in one device.

It will show you how to send temperature and humidity values wirelessly to adafruit io from a dht22 sensor. 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. While the sensor is good up to 125 c the cable is jacketed in pvc so we suggest keeping it under 100 deg c. Adafruit lsm9ds0 accelerometer gyroscope magnetometer adafruit lsm9ds1 accelerometer gyroscope magnetometer how does it work.

Humidity temperature barometric pressure. The pct2075 by nxp is a pin compatible drop in replacement for a very common i2c temperature sensor the lm75. This guide is part of a series of guides that cover the basics of using adafruit io. 381 this is a pre wired and waterproofed with heat shrink version of the ds18b20 sensor.
