I want to build the monitoring system for the ribbon saw (KASTO HBA-430) with KC868-A8 device.

I have difficulties in understanding whether your device can measure the frequency.

I want to measure the rotation frequency of the pulley of the ribbon saw.
At the moment, the rotation frequency of the pulley is measured by the CF5135C-Z device with sensor NJK-5002C NPN NO.

Typical frequency range is 0..120 rpm.


Does your device support the frequency measurement mode by the Digital Input pin?
Does your device support the frequency measurement mode by the some I2C external device?

Which of your devices can measure frequency using a sensor like NJK-5002C?

HI,
I can't run any code from arduino.

I run the ide with arduine on windows 10.
I installed the drivers that I read in a post for the usb port.

The error:

esptool.py v3.0-dev
Serial port COM3
Traceback (most recent call last):

Dear Kincony,

I Would like to try to aquire one sample for of KC868-A4 to learning and testing for home automation (type of use A).

Best Regards.

hi, first of all thanks for the great product. it fits 100% to our requirements.

we use the board togehter with home assistant and ESPhome V 2023.5.2.

We like to messure Temperature via NTC sensors. We use this settings.

10K NTC
9.89K resistor
5V DC Power Supply
Connected on INA1

We get a wrong temperature reading. If we connect the 5V DC direkt to the  INA1 input we get max. 3.03V on the GPIO36. As we see you use a LMxxx bevor the ESP32. Is the conversion of the 5V linear
to the 3.3V input of the ESP32? Do you have any hints? as the  reference_voltage we use 3V because of the limitation of the ESP32.

Giuseppe

hello kincony

I have some problem when I add analog in my yamal file 

--give me wrong when I make restart

--and all mqtt stop 

---when i remove all thing good

Hello,

I am very interested in Kincony products and features and would like to explore all the possibilities in practice.

I would like to apply with condition A as I plan to use the KC868-A4 kit for personal training and development. I am very excited to explore the possibilities of these products and gain hands-on experience with them. I would like to try to implement various projects and in the future to purchase a large controller to automate other processes.

Best wishes,
Aleksandra

Hello,

How would you recommend wiring the PIR sensor AM312 to the KC868-A8 v1.5?
I tried 
A8       AM312
GRD to GRD
Vcc  to  VCC
S4   to  out

   
   

Hello.

I want to use the KC868-A4 for manual remote control of the boiler from an Android device.
Inputs A3 and A4 and outputs DA1 and DA2 are for power conveyor and exhaust fan control.
Inputs A1 and A2 are for temperature sensors. A DS18b20 sensor is also used for temperature control.
Digital inputs and relay outputs are for switching water pumps.

It is better to use port forwarding, VPN or DMZ than a cloud service to connect to the Internet.

I would like help in creating a program.
