Universal WiFi Data Collector

I use these to monitor the temperature on my solar hot water system, as well as run an incubator, monitor weather sensors, and run the oil stove in my shop.

This is a sensor "aggregator". Essentially it collects information from physical sensors and displays them on a wifi accessible web page.

It does not store information, as such, on the device.

Available sensors:
6 analog (0-5V) channels
- usable for temperature or humidity sensors, or anything that has a proportional analog output voltage
2 digital counter (streaming number) channels
- useful for flow counters or rain gauges or the like
10 (up to) 1wire temperature sensor


2 thermocouple inputs (may be noise issues depending on your configuration)

Available outputs:
4 digital output (on/off) available. (two on prototype)

For sale is the aggregator. You configure it to your wifi network, then it will display the sensor data on a web page. You then hit that web page with a script that extracts the information you are interested in, and feeds that information to your logging software.

For instance, in my application, I use a script running on a Linux machine to collect the temperatures from my solar hot water system, and I use MRTG (Cacti would also work) to chart and record those numbers.

You can also toggle the output of four (two on prototype) pins with a "cgi" command from your storage computer. So, for instance, I can poll the aggregator and determine the current temperature and humidity in my incubator, and then turn the heaters on or off based on that (with solid state relays).

I will provide examples of how to set up up the logging software with the purchase. You will have to know how to set up MRTG or Cacti or whatever software you are wanting to use to collect and record the information provided by this device.

What is included: Data Collector, power supply, one analog sensor, one 1-wire sensor.

NO SOFTWARE is included. The examples I provide are for Linux.

NOTE: The prototype for sale here has a minor issue with noise on the 1-wire line causing issues with the thermocouple readings in some installations. If this issue crops up you will need to add filter capacitors to your thermocouples, and electrically isolate them from what you are sensing.
