It is specifically designed to interface with Wheatstone Bridge sensors (load cells), which are the standard components found inside digital bathroom and kitchen scales.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e \u003cbr\u003e\u003cstrong\u003eKey Features \u0026amp; Capabilities:\u003c\/strong\u003e \u003cbr\u003e• 24-Bit Precision: This offers an incredible level of detail. To put that in perspective, a standard Arduino has a 10-bit ADC (1,024 levels), while the HX711 has over 16 million levels of resolution. \u003cbr\u003e• Dual-Channel Input: It features two channels (A and B). Channel A is typically used for the main scale, while Channel B can be used for a second sensor or system monitoring. \u003cbr\u003e• Programmable Gain: It includes an internal Low-Noise Amplifier (LNA) with a gain of 128x. This boosts the tiny electrical signal from the load cell so it can be accurately digitized without losing data to electrical noise. \u003cbr\u003e• No Dual Power Supply Needed: It operates on a simple 2.7V to 5.5V range, meaning it can be powered directly from your microcontroller without needing specialized power circuitry.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e \u003cbr\u003e\u003cstrong\u003eWorking Principle:\u003c\/strong\u003e \u003cbr\u003eLoad cells contain strain gauges that change resistance when stretched or compressed. The HX711 measures the resulting voltage difference, amplifies it, and sends the data to your board via a two-wire serial interface (Clock and Data). \u003cbr\u003eTechnical Specifications: \u003cbr\u003e• Differential Input Voltage: ±40mV (at 128x gain). \u003cbr\u003e• Data Rate: Selectable 10SPS (samples per second) or 80SPS. \u003cbr\u003eo Tip: Use 10SPS for maximum stability\/accuracy and 80SPS for fast-moving applications. \u003cbr\u003e• Current Consumption: \u0026lt; 1.5mA during normal operation (ideal for battery-powered IoT scales).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e \u003cbr\u003e\u003cstrong\u003eBest For: \u003c\/strong\u003e\u003cbr\u003eThe HX711 is the go-to module for digital kitchen scales, industrial weighing systems, smart beehives (to monitor honey production), and automated inventory bins. \u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46397421125831,"sku":"TE-LOADC-057","price":57.78,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/HX711Dual-Channel24BitPrecisionADweightPressureSensor_1.png?v=1776666123","url":"https:\/\/shop.tinkedge.tech\/products\/hx711-dual-channel-24-bit-precision-a-d-weight-pressure-sensor","provider":"TinkEdge","version":"1.0","type":"link"}
