OLED Formaldehyde Temperature and Humidity Detect Electronic DIY Production Parts SolderingTraining DIY Kit

Note This product is a DIY kit and needs to be soldered and assembled by yourself Product description The electrochemical formaldehyde module is a general purpose miniaturized module Using the electrochemical principle to detect CH20 in the air it has good selectivity and stability Built in temperature sensor for temperature compensation at the same time it has digital output and analog voltage output which is convenient to use Electrochemical formaldehyde module is a general purpose gas module designed and manufactured by closely combining mature electrochemical detection technology with sophisticated circuit design Pay attention to the measurement please close the doors and windows as much as possible and do not approach people to breathe or bring wind Large turbulence will fluctuate from time to time and the result is most accurate after standing for half an hour After the measurement is completed please put the instrument into the box and place it in a place with a relatively low formaldehyde concentration Because it is an electrochemical sensor a place with a high formaldehyde concentration will easily overload the sensor for a long time resulting in a long time of zero in the next measurement Kit parameters Product name OLED formaldehyde temperature and humidity detector kitWorking voltage DC 5VAppearance size 70mm 45mm 25mmProduct weight 26gFormaldehyde detection range 0 5 000 mg m3Interfering gases alcohol carbon monoxide The sensor is very
