DESCRIPTION

Put a temperature meter anywhere with this very handy display. This panel meter

displays the temperature of the attached waterproof 1% thermistor in °C. It does

require a DC voltage to run, at 4.5-30VDC. It has reverse polarity protection in case

you swap the power leads by accident.

To use, simply connect the thin red wire to a positive supply, and the thin black

wire to ground. Then tape the black thermistor bulb to whatever you want to

measure - or leave it loose to measure ambient temperature. The display has a

microcontroller that will read thermistor resistance and display the corresponding

temperature from -30°C to 70°C with 1 °C precision on a 3-digit 0.56" tall

7-segment display. The meter draws 3-4mA to power the microcontroller and

display. This particular LED display is a nice vivid blue, which we found very

readable. To mount to your enclosure, simply cut a 45.5mm × 26.5mm rectangle

and snap it in.

This meter can only display the temperature in Centigrade °C, it cannot be modified

to °F and we do not have a version that is °F.
