Inkbird ITC-308 Digital Temperature Controller Thermostat Dual Relays He

Down to £21.37 from £29.99 @ Amazon

Good bit of kit,getting ready for spring.

 

I have those for my indoor set up. It pays for itself because it helps me get a jump on our short growing season. No more frying seedlings!

 

I agree with the others - great kit and excellent price.

 

Hi,

Yes, that is a very good price to what they and similar units used to be a couple of years ago.

Having 4 such stats in our greenhouse would have been quiet expensive so built our own 4 way controller which has the advantage of a remote screen on the desktop so saves us having to go out in the really bad weather to verify everythings ok.

Able to fall flat on the face in dry weather on the patio flags , never mind rain ,ice and snow ! .....

 

The Inkbird is a really good piece of kit. Built like the proverbial brick house, and after three years very reliable. I have it connected to an oil filled radiator, coming on at 5°c and off at 9°c. Very easy to set up limits, when you get used to some of the peculiar LED letters on the readout.

 

Hi @ricky101 did you use arduino for that controller? I'm just prototyping a sensor system for logging moisture, light etc on one so I'm interested.

 

Yes , its the Arduino, used to use Microchips Pics with Assembly code, but the Arduino makes everything so much easier, no separate programmer needed.

Have only used NTCs and DS18B20 for Temperature and DHT11/22 sensors for Humidity in the greenhouse and used float switches and optical water level sensors in the fish tank.

Considered moisture sensors but the more I looked at them, they seemed very hit and miss and difficult to get an even control.

When you say light, did you mean time control /dimming or intensity/spectrum control using a sensor ? only used the former.

So much you can do with these little Arduino modules, the greenhouse control uses basic 128x64 screen but for the fish tank we are using 320 x 240 with touch control, though the simple 2x16 lcd is still good for many things .

Its only simple code / circuity but happy to help with anything we can...
