prodef PH Value Detection Module Liquid Detect Sensor Soil Water Monitoring Control Component intelligence

Feature:1. QUICKLY RESPONSE TIME: The sensor module has quickly response time, low power consumption, convenient use and long use time2. TWO TRIMMERS: There are two trimmers on the circuit board. One is to achieve offset adjustment by removing the pH probe and shortening the BNC connector with a wire(closest to the BNC connector). Another trimmer is the upper threshold of the digital output pin3. PCB DOUBLE SIDED BOARD: Using 1.6mm thick PCB double sided board, sturdy and durable, possess long service life4. LONG RUNNING TIME: PH value detection module come with large heat dissipation area, stable operation and long running time5. PH0-14 DETECTION CONCENTRATION RANGE: Detection concentration range from PH0-14, detection temperature range is 0-80℃, analog voltage signal output methodSpecification:Item Type: PH Value Detection ModuleMaterial: PCBPurpose: Sensor moduleHeating Voltage: 5±0.2V (AC DC)Working Current: 5-10mADetection Concentration Range: PH0-14Detection Temperature Range: 0-80℃Response Time: ≤5SStability Time: ≤60SComponent Power Consumption: ≤0.5WWorking Temperature: -10~50℃ (nominal temperature 20℃)Working Humidity: 95%RH (nominal humidity 65%RH)Output Mode: Analog voltage signal output.Package List:1 x PH Value Detection ModuleNote:1. Note that the buffer solvent needs to be purchased after purchasing the PH sensor (note that this is not sold and needs to be purchased locally, thank you).2. The pH electrode probe must be calibrated with standard buffer solution before each use, and the electrode probe cannot be tested continuously for a long time, thus shortening its life.3. If you are using granular products such as photon or argon, please pay attention. This is a hardware problem, the analog port will fluctuate with the ghost voltage. Under these low voltage readings, this fluctuation is enough to make your pH swing at 0.7 or above. In order to solve this problem, you need to add a 0.1uF cap between the used and grounded analog port.
