Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

You also need to select the transistor by the type of fan that you use. In my case I used the well-known BD139 transistor and a 9V battery to provide power to the fan and transistor. The LM35 ...

Dippy birds are the toys that teeter-totter back and forth as the beak of bird-shaped body dips into a container of water. The felt covering the beak and head picks up water and, through evaporati… ...

The datasheet says the AHT10 is a digital temperature and humidity sensor embedded for reflow soldering. The dual-row flat leadless SMD package has a 4x5mm bottom and a height of 1.6mm. The AHT10 ...

The Arduino compatible Pax Instruments T400 Temperature Datalogger is now available to purchase priced at $175 from Adafruit. If you liked this you might also be interested in building an Arduino ...

You'll need an Arduino along with a bunch of various sensors to get the project rolling, and once it's all set up you'll have a simple, but cheap system to monitor your home. Head over to ...

The sensor has an untrimmed inaccuracy of 0.9°C, improving to 0.5°C after a single-point PTAT trim. Further compensation for resistor variation achieves a final inaccuracy of 0.1°C. An energy ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...
