This allows it to be connected directly to analog inputs on microcontroller boards such as Arduino or to common single-board computers, without requiring a level shifter.\u003c\/p\u003e \u003cp\u003eThe sensor uses galvanic isolation via an optocoupler. This means that the measured voltage and the logic circuit have no direct electrical connection. As a result, there is no risk of voltage surges damaging the control electronics, for example when an inductive load is switched on.\u003c\/p\u003e \u003cp\u003eTypical applications include monitoring batteries or power supplies, measuring voltages in charge controllers, or monitoring motor voltages in autonomous vehicles. For example, when building a battery management system, it can be used to continuously monitor the state of charge and trigger a shutdown if a threshold value is undershot.\u003c\/p\u003e \u003cp\u003eA supply voltage of 3.3 to 5 volts is required for the logic side. In addition, measurement accuracy of approximately 2 percent is recommended, allowing voltage changes to be detected reliably.\u003c\/p\u003e \u003ch3\u003eSafety information\u003c\/h3\u003e \u003cp\u003eThe module is not intended for installation in household mains circuits and is intended exclusively for prototyping, testing, and development purposes. Before taking measurements in 24 V industrial networks or on other live conductors, consult a qualified electrician. Work on or near electrical installations is reserved for qualified electricians.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x voltage sensor, 25V\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65998297596253,"sku":"F23106636","price":1.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/spannungssensor-25v-funduino-9406113.png?v=1791496446","url":"https:\/\/funduino.com\/en\/products\/voltage-sensor-25v","provider":"Funduino","version":"1.0","type":"link"}
