The module receives the voltage signal from a load cell, amplifies it internally, and provides the measurement result as a digital value that can be read by a microcontroller.\u003c\/p\u003e \u003cp\u003eTwo independently configurable input channels enable flexible measurement setups. Channel A allows a choice between 64x and 128x gain, corresponding to input ranges of ±40 mV or ±20 mV. Channel B operates with a fixed gain of 32x and can be used for a second sensor. The output data rate can be switched between 10 Hz and 80 Hz to adapt the measurement speed to the application.\u003c\/p\u003e \u003cp\u003eCommunication with the microcontroller requires only two wires. The controller sends clock signals, and the module then returns the 24-bit measurement values serially. The data rate can also be adjusted via the same clock line. Capacitors already soldered onto the board and an internal regulator eliminate the need for external circuitry.\u003c\/p\u003e \u003cp\u003eThe module can be used wherever small loads or forces need to be measured, for example in electronic scales for weighing food or people, or in industrial load cells. The setup is minimal: connect the load cell, connect four wires to the microcontroller, and you are ready to go.\u003c\/p\u003e \u003cp\u003eOperation requires a power supply between 2.6 V and 5.5 V, as well as compatible interface software for the development board being used. Compatibility with Arduino and Raspberry Pi is provided when the respective software libraries are included.\u003c\/p\u003e \u003ch3\u003eSafety notice\u003c\/h3\u003e \u003cp\u003eThe module is not intended for connection to household appliances or industrial power supplies and may be used exclusively for prototyping, testing, and development purposes. Calibration is required before the first measurement operation. If you have questions about commissioning or the correct connection of load cells and the power supply, consult a qualified electrician.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003eHX711 - 24-bit A\/D load cell amplifier\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65997807157597,"sku":"F23106474","price":1.4,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/hx711-24-bit-ad-waegezellenverstaerker-funduino-7755971.jpg?v=1791473951","url":"https:\/\/funduino.com\/en\/products\/hx711-24-bit-a-d-load-cell-amplifier","provider":"Funduino","version":"1.0","type":"link"}
