Co2(ppm)/temp/Rh logger for cheap
- Thread starter overbudjet
- Start date
nice find. i wonder if linux is supported. personally, though, i prefer homemade sensors.
this is what i've been planning on building for a little while. it looks like all the parts for about 10-20 of these would cost under $150, which would be plenty to map/log out just about anything i wanted temperature-related in my setups. it is only temp, though, unfortunately.

Really nifty linux-based wireless rH sensor

If you have a technical mind, which most of us do, you can usually build a better, cheaper version of most things on the market

CO2 sensor - environmental data logger
CO2 sensor - environmental data logger
I'm currently working on a low-cost datalogger using a commercially manufactured device with onboard webserver.
Sensors are Telaire 6004 NDIR CO2 sensor with analog and UART outputs (actually interfacing the 0-4vdc output w/arduino/Amtel circuit for an easy co2 level control - 0-4v can also be connected to a PLC, or any control device or system with analog input for CO2 control).
Temp/RH sensor is Sensirion SHT75 which uses I2C communication. No analog outputs for temp/RH.
Both of these sensors can easily be connected to an Atmel MEGA microcontroller programmed with the Arduino IDE.
I'll work on that later but I just purchaced a few hundred of the last remaining PureTrack NOSE units in which somebody has already done the work. I'll be flipping these with data logging software for a couple hundred dollars, CO2 control circuit optional. (device connects to your local network and/or internet via Ethernet, cat5).
Software logs data and allows you to view current levels remotely (or with LCD screen). Also sends text or email messages if any level goes outside your preset range.
Here's a pic of the device:
Screenshot of two units:
The Circuit board. See Telaire 6004 NDIR CO2 sensor (gold) and the Sensirion SHT75 Temp/RH on the ribbon-cable at the top of pic (mounted on ribbon-cable to prevent the heat from circuit board from interfering with accurate temp reading).
The screenshot above the circuit board pic is the flash display from the onboard webserver - only a web browser is required to view right out of the box.
The data-logging software is in beta testing.
The parameters, including averages are available via http by typing the address (192.168.1.51 in this case) followed by sens-1, sens-2 or sens-3 > I'm working on the code but if anybody has specific skills doing this sort of thing, please email or PM (I'm very happy to pay for services rendered and have more projects in the works).

PS: That MG811 in the post above is not a very accurate sensor. The Telaire 6004 costs a bit more (allied electronics sells them) but it's well worth it. There are also some telaire copies out there (Hanwei MH-Z12) which has UART and analog communication onboard and is priced closer to MG811 model but is a much better product. Futurlec.com used to sell the MG811 for about $12 which is more on par with its value.
There is also a guy on FeeBay selling some Telaire modules for about $40 (they sell for like $120 elsewhere). They are OEM modules and I'm not sure if they have 0-4v output or PWM (pulse-width-modulation) but either can be used with arduino, black, Rasberry PI or any of the available microcontrollers available. (check out the BLACK from TI - It's supposed to be the best of both arduino and rasberry pi and priced at $40 from Texas Instruments. Runs Linux and has some other IDE available. I've got a couple coming.)

dxco! That is unreal. I come from a software electronic engineering background but unfortunately I av no time to help you with code... Love this tho.. Best thing about DIY sensors is that you can easily fix it if a component breaks down..
I wonder could we build a proper diy iponic with Co2 ppm meter, RH meter, temp, and then maybe throw in a remote PH meter, ppm meter with all the bells and whistles ...alarms/shutoff/doser etc..
Sell them on ebay for icmagers/pot community

This is the one I'm looking at getting. Data logs every 30 minutes, so 48 logs every 24 hours.
Temp, humidity and co2.

Thanks overbudjet. After finally getting time to look into the Green Eye, that's what I went with. Much nicer than the Autopilot I was going to get.
You are welcome Sir.
