temperature sensor

Question

Looking for a temperature sensor that can wifi information to a web based platform. Hoping to know when my pipes are about to freeze again, so I can avoid the damage!

A low-cost solution is to use an ESP8266 with a temperature sensor. There are many examples on the net.

Simplelink SensorTag - TI.com is currently Bluetooth enabled and soon WiFi. Clem

I second the ESP8266, I have been using these for a number of projects lately and they are an inexpensive (sub $10) solution to get a wifi connected device on your network for a variety of monitoring tasks. You have the option of programming them in the Arduino IDE, using the Arduino framework, if you would like.

Great suggestion, Doug.

I don't know of any sensors that are WiFi enabled, but you could rig up a Raspberry Pi with a DS18B20 or a DHT11 and have the Pi send via WiFi to a web platform. I have used the DS18B20's before and used a Pi to send an SMS message to a cell phone and it wasn't too difficult to make it work. It shouldn't be hard to make the Pi send to your web based platform.

You could use a ESP8266 with a temperature sensor attached to it. Then use a Raspi with a LCD or a even the 7-inch touch screen and design a GUI for use with it to display the current temperature and any warnings if the temperature reaches a low enough temperature. The ESP8266 can run off a couple AA batteries (or even a coin cell) for a fair length of time especially if you only send data when you need to. Which would help if the pipes are in a location where you may not be able to easily get a power supply put in. Hope this helps
