Building Your Own Personal Weather Station‘ – and of course we appreciate the mention of our pre-packaged waterproof DS18B20 digital sensor (shown below).
You can build a personal weather station (PWS in the lingo) yourself using parts available online from vendors like Adafruit and Ambient Weather. The basic structure is a pole, a housing for the electronics, and motherboard to run the show. Yes, you need enough knowledge to get the motherboard working. But a proliferation of simple tools for iOS, Android, and desktop computers means just about anyone with a shred of technical acumen can do it.

Waterproof DS18B20 Digital temperature sensor + extras: This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don’t get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems. Read more.
