I can’t find any datasheet or part number for my temperature sensor. All the air conditioner having a sample type of sensors.

Hi,
I am having an air conditioner temperature sensor for ambient temperature measurement, which value is not in linearity. How to make out the temperature by using only the ADC Value to get degrees in the C code like any formulas.
For a example this is my temperature sensor chart:
Celsius...
It is not matter of type cloth. Mainly I want sense the cloth weight, it may be whatever fabric. I am sure there is no any sensors are not fixed. They are identifying by only agitation method (By rotating CW and CCW or rotating at Spin).
Sure, i know they are not using pressure sensor for the cloth load sense. The pressure sensor works only at water fill. If the water rises means the bottom side of the air will be pushed to the Pressure sensor, then we can identify the water level. What will be the solution to identify the cloth...
Thanks for you all reply....
In my whirphool washing machine, when load sensing starts the motor will run anti-clockwise (like spin) upto 8 seconds. Only three wires are flowing to the motor from the PCB.
1. Newtral
2. Motor CW
3. Motor CCW
At motor side capacitor is connected in parallel to...
Then what will be solution?.
I have seen in some of the washing machine, they are not using any special sensors for measuring the cloth load. How they are measuring the cloth load?
I am working on the Automatic Washing machine project. I want to sense the Cloth load in the drum. I am sensing the wash motor current to measure the cloth load. Once i got the cloth load, I will take that much water quantity,rinse and spin time. What is my problem means:- In my wash motor with...
Hi,
I interfaced with the ACS71020 with the Arduino board. But still, I can't' get the actual values.
This is my Arduino code:-
/* ACS71020 Arduino Programming Code
* This code will work for Arduino UNO
* Supply Voltage is 3.3V, ACS71020KMABTR-030B3-I2C
* SCL Pin = A4 Analog Pin
* SDA...
sorry...It's 1/2^15
If I read other address like EEPROM data of the ACS71020 means, data is constant and matching. If I try to read only the voltage and current - the data are not constant. Help me to solve this problem....
Hi,
Finally, I communicated with the ACS71020 using 0x60 (96 decimal) as a slave address. Random data is coming from the CHIP when I read the address 0x20 to get voltage. But I can't figure it out. In the datasheet mentioned to get the VRMS:-
"This field is an unsigned 15-bit fixed point...
For an Example:
I want to run the Washing Machine - Wash motor, in the Wash motor there is no RPM feedback. Only the Supply line three wires are present in the motor. I want to run the motor at the same RPM whatever given User Load. In this scenario what is the solution to run the motor at same...
Hi,
I am trying to communicate with the ACS71020 with STM32 MCU. I used 0xC0 as a Slave address, but the device not responding.
HAL_I2C_Mem_Read(&hi2c1,0xC0,0x20,1,&data,1,100);
Always i am getting '0' only. I made DIO0 & DIO1 pulldown externally. Help me to solve this problem.
Thanks for your reply.
But in my application, the DIO0 is used for Voltage zero crossing and DIO1 for Over Current. If I Disable I2C slave address selection circuit means. Then what will be the slave address?.
