Description: Channel A or B can choose different input, the gain is 64 or 128 in the low-noise programmable amplifier Stabilized voltage supply offered by chip can directly supply power for external sensor and A\D converter Clock oscillator doesn't need any external device. If necessary, it can use external crystal oscillator or clock Automatic reset function, all control signals are driven by pins, without programming register of inner chip Alternative 10Hz or 80Hz of output data rate Specification: Electronic scale is commonly seen with function of weighting, this starter help you to DIY your own electronic scale with what you have learned Easy to make an open source electronic scale with a weighting module, an AD chip (hx711), and Arduino with corresponding library It uses the strain gauger to measure deformation caused by pressing metal when weighting force, measure the force bore by the sensor HX711 is a chip of 24 bit A\D converter, designed for high precision weighing sensor, features high integration, quick response and strong anti-interference, integrated external circuit needed by other chips including stabilized voltage supply and on-chip clock oscillator, it decreases cost of complete machine of the scale, and improve its performance and reliability, the interface and programs of this chip and MCU chip are very simple Stabilized voltage supply offered by chip directly supply power for external sensor and A\D converter, no need for additional analog power on main board, all control signals are driven by pins, without programming register of inner chip Input and select switch to choose arbitrarily channel A or B, connecting it to a low-noise programmable amplifier The gain in channel A is 128 or 64 bit, and its corresponding amplitude of different input signals in full loaded is respectively ±20mV or ±40mV The gain in channel B is fixed 32, used to detect system parameters Clock oscillator doesn't need any external device Automatic reset simplifies initialization when opening up Material: FR-4 Epoxy Glass Fibre Board Size: Approx. 6.9 x 5.3 x 1.4 cm/ 2.72 x 2.09 x 0.55 inch Package Includes: 1pcs Keyestudio UNO board 1pcs I2C 1602 LCD 1pcs Keyestudio digital push button 1pcs Kyestudio HX711 Weighing Module 1pcs 5kg Rheostat sensor 1pcs Tabula board (upper board) 1pcs Tabula board (bottom board) 1pcs Keyestudio R=120mm bearing acrylic board 1pcs Keyestudio 15 * 11 * 4 acrylic board 10.4mm spacer 1pcs 50g Weight 1pcs 100g Weight self-adhesion 3m crashproof transparent colloidal particle 10pcs 54 granules 23pcs M3 x 6mm round head screws 22pcs M3 nickeling nuts 2pcs M4 x 10mm flat head screws 8pcs Hexagonal copper fistulars M3 x 10mm 3pcs Hexagonal copper fistulars M3 x 40mm 20pcs Female to female dupont lines15cm 1pcs USB cable 1pcs18650 Battery case Note: Please allow 1-3mm differs due to manual measurement.
