The voltage and current resolution can reach 4mV and 1mA respectively. Under the full scale measurement condition, the maximum relative error of voltage and current measurement can be superior to ±0.2%. It also provides four I2C addresses that can be configured via the 2P DIP switch. The module accurately measures bi-directional high-side currents (current flowing through the power supply or battery positive), which is especially useful in solar or battery fuel gauge applications where the battery needs to be charged and discharged. This status can be simply determined by positive or negative current readings. In the motor applications, the current can be monitored in real time by monitoring whether the motor current is too large due to overload. In addition, you can use this module to measure the power consumption of various electronic modules or the entire project to evaluate battery life.\u003c\/span\u003e\u003cimg style=\"font-size:

The liquid level sensor is installed under the container (high level and low level). No need to bore a non-metallic container, easy to install. It can detect liquid levels of various toxic substances, acid, alkali, and all kinds of liquid in high-pressure airtight containers. It can be widely used and has no special requirement for the liquid medium and material of the container.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eApplications:\u003c\/div\u003e\n\u003cdiv\u003eWater tower\u003c\/div\u003e\n\u003cdiv\u003eSewage treatment\u003c\/div\u003e\n\u003cdiv\u003eDrone irrigation\u003c\/div\u003e\n\u003cdiv\u003eMedical equipment\u003c\/div\u003e\n\u003cdiv\u003eAquarium\u003c\/div\u003e\n\u003cdiv\u003eSmart Appliances\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eFeatures:\u003c\/div\u003e\n\u003cdiv\u003eThe non-contact liquid level sensor is applicable to non-metallic containers without direct contact with the liquid, not affected by scale or other impurities.\u003c\/div\u003e\n\u003cdiv\u003eHigh stability, high sensitivity.\u003c\/div\u003e\n\u003cdiv\u003eCompatible with most 5 ~ 24V power adapters.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003eSpecifications:\u003c\/div\u003e\n\u003cdiv\u003eModel:XKC-Y26 NPN\u003c\/div\u003e\n\u003cdiv\u003eInput Voltage (V):5~24\u003c\/div\u003e\n\u003cdiv\u003eCurrent Consumption (mA):5\u003c\/div\u003e\n\u003cdiv\u003eMax Output Current (mA):1~100\u003c\/div\u003e\n\u003cdiv\u003eResponse Time:500mS\u003c\/div\u003e\n\u003cdiv\u003eOperating Temperature Range (°C):0~85\u003c\/div\u003e\n\u003cdiv\u003eWorking Humidity Range:5~100%\u003c\/div\u003e\n\u003cdiv\u003eMaterial: ABS\u003c\/div\u003e\n\u003cdiv\u003eCable Length (cm):49\u003c\/div\u003e\n\u003cdiv\u003eLength (mm):18\u003c\/div\u003e\n\u003cdiv\u003eWidth (mm):13\u003c\/div\u003e\n\u003cdiv\u003eHeight (mm):11\u003c\/div\u003e\n\u003cdiv\u003eWeight (gm):45\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003ePackage Includes:\u003c\/div\u003e\n\u003cdiv\u003e1 x XKC-Y26 NPN 24V 50CM Intelligent Non-Contact Liquid Level Sensor\u003c\/div\u003e","brand":"Others","offers":[{"title":"Default Title","offer_id":42292889485503,"sku":"MLE03481","price":500.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/sg-11134201-7reor-m1ns4zhcbrmm18.jpg?v=1735814422"}],"url":"https:\/\/makerlab.ph\/collections\/liquidflow-sensors.oembed","provider":"Makerlab PH","version":"1.0","type":"link"}
