the specific steps of the program are as follows:
step 1: how to calculate the supply voltage of the pressure sensor 12
The HX711 module can generate VAVDD and AGND voltages, i.e., the E + and E-voltages on the HX711 module; the voltage is calculated by VAVDD ═ VBG (R1+ R2)/R2; VBG is the module reference voltage 1.25V, R1 ═ 20K, R2 ═ 8.2K, and therefore VAVDD ═ 4.3V.
(to reduce power consumption, this voltage is only output at the sampling instant, so the value read with a multimeter may be less than 4.3v, since the multimeter measures the effective value.)
Step 2: how to calculate the maximum AD output
The maximum output voltage of the sensor of 3Kg under the power supply voltage of 4.3V is 4.3V 1 mV/V4.3 mV, after 128 times of amplification, the maximum voltage is 4.3mV 128 550.4mV, and the maximum 24bit digital value output after AD conversion is as follows: 550.4mV 224/4.3V 2147483.
And step 3: how data is transformed in a program
In the program, the result is HX711_ Buffer ═ HX711_ Read (); obtaining the AD value of the current sample, wherein the maximum AD value is 2147483, storing the current sample in the long type variable HX711_ Buffer, and dividing the current sample by 100 to facilitate subsequent calculation; weight _ Shiwu — HX711_ Buffer/100; weight _ Shiwu is a maximum of 21474.
And 4, step 4: how to convert the AD values back to gravity values.
Assuming that the gravity is AKg, (x <3Kg), the measured AD value is y, the 3Kg sensor output, the voltage sent to the AD module is AKg × 4.3mV/3Kg ═ 1.43AmV, after 128 times of gain, 128 × 1.43A ═ 183.46AmV, the voltage is converted into a 24bit digital signal of 183.46AmV × 224/4.3V ═ 715801.8A, so y ═ 715801.8A/100 ═ 7158.018A, so that a ═ y/7158.018Kg ≈ y/7.16g is obtained, and therefore, a calculation formula Weight _ Shiwu ═ is (unsigned) ((flow) Weight _ Shiwu/7.16+0.05) in the program is obtained; /+0.05 is to round off the percentile.
Special attention is paid to: because the slope characteristics of the different sensors are different, each sensor needs to correct the divisor 7.16. This value is increased when the weight tested is found to be excessive. If the measured weight is smaller, the change value is decreased. Depending on the linear slope of the sensor. Each sensor is calibrated individually. (the volume sensors are all pressure sensors 12)
