{"product_id":"panel-temperature-meter-30-to-70-c","title":"Panel Temperature Meter \/ -30 to +70 °C","description":"\u003cp\u003ePut 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.\u003cbr\u003e\u003cbr\u003eTo 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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThis 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.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cp\u003eDimensions:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 48x29x21mm\u003c\/li\u003e\n\u003cli\u003eDigit size: 14mm\/0.56\" high, blue LEDs\u003c\/li\u003e\n\u003cli\u003ePanel cutout: 45.5mm x 26.5mm\u003c\/li\u003e\n\u003cli\u003ePower lead length: 15cm\u003c\/li\u003e\n\u003cli\u003eThermistor lead length: 12cm\u003c\/li\u003e\n\u003cli\u003eRefresh rate: about 2 Hz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePower specifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e4.5V to 30V DC input\u003c\/li\u003e\n\u003cli\u003e0.1V precision\u003c\/li\u003e\n\u003cli\u003e3-4mA draw\u003c\/li\u003e\n\u003cli\u003eBlue LED display\u003c\/li\u003e\n\u003cli\u003eReverse polarity protected\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":56199967408450,"sku":"jhd1789699823920","price":9.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1013\/4392\/0450\/files\/panel-temperature-meter--30-to-70-c_1.jpg?v=1789699830","url":"https:\/\/bouclebox.shop\/products\/panel-temperature-meter-30-to-70-c","provider":"My Store","version":"1.0","type":"link"}
