50kg E-Shaped Load Cell Range: 50kg E-Shaped Load Cell Size: 30mm*25mm Load Cell with Foot Pads and Bracket Size: 44*42*17mm Weight: 62g (15.5g*4pcs) Cable length: 35cm Output Sensitivity: 1.0±0.2mV/V Zero Output: ±0.5mV/V Non-Linearity: 0.3%F.S Hysteresis: 0.3%F.S Repeatability: 0.3%F.S Creep: 0.05%F.S Output (Input) Impedance: 1000±5%Ω Operating Temperature: -10C~+50°C Zero Temperature Drift: 0.3%F.S Temperature Sensitivity Drift: 0.3%F.S Insulation Resistance: ≥2000MΩ Excitation voltage: 3-10V DC Safe Overload: 120%F.S Matching Error: 0.1%F.S Overall Accuracy: 0.3%F.S The sensor is a group of half-bridge strain gauge, there are 3 ways to use it: 1. Use one sensor with an external resistor to form a full-bridge measurement, the range of a sensor range: 50kg. External resistance on the higher requirements. 2. Use two sensors to form a full-bridge measurement, measuring range for the sum of the two sensors: 50kgx2 = 100kg 3. Use four sensors to form a full-bridge measurement, measuring range for the sum of four sensors: 50kgx4 = 200kg HX711 AD Weight Module 1. The module uses 24 high-precision A/D converter chip hx711, is designed for high-precision electronic scale and design, with two analog input channels, the internal programmable gain amplifier integrated multiplier 128. 2. The input circuit can be configured to provide a bridge voltage electrical bridge (such as pressure, weight) sensor model is an ideal high-precision, low-cost sampling front-end module. 3. Operation supply voltage range: 2.6 - 5.5V, Operating Temperature Range:-20 degree to +85 degree. 4. Simple digital control and serial interface: pin-driven controlsno programming needed. 5. Selectable 10SPS or 80SPS output data rate, Simultaneous 50 and 60Hz supply rejection. 6. Current consumption including on-chip analog power supply regulator: normal operation<1.5mApower down<1uA. HX711 Features: Two selectable differential input channels On-chip active low noise PGA with selectable gain of 64 and 128 On-chip power supply regulator for load-cell and ADC analog power supply On-chip oscillator requiring no external component with optional external crystal On-chip power-on-reset

• A single half-bridge load cell cannot work independently as it lacks a full bridge. It needs auxiliary circuits to form a full bridge for signal output, or multiple even-numbered half-bridge cells used in combination. Four half-bridge cells can be combined into one full bridge, normally mounted symmetrically on four corners of the weighing platform.
• 50kg E-shaped load cell Voltage: DC3-10V, load cell with foot pads and bracket Size: 44*42*17mm, Weight: 62g (4pcs), Cable length: 35cm
• This module uses 24 high precision A/D converter chip hx711, specially designed for the high precision electronic scale
• HX711 Module Operation supply voltage range: 2.6-5.5V, HX711 On-chip active low noise PGA with selectable gain of 64 and 128
• How to change the rate of HX711? The output data rate (frequency) of the HX711 module can be switched by the level state of its 15th pin (RATE pin). Set this pin to high level to change the output data rate from the default 10Hz to 80Hz.
