{"title":"Panel Temperature Meter / -30 to +70 °C","handle":"panel-temperature-meter-30-to-70-c","url":"/products/panel-temperature-meter-30-to-70-c","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.","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12779,"title":"Default Title","sku":"AF-576","price":19.41,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
