  KC868-A16 - Maximum output current per channel
Posted by: iwjcs - 04-11-2025, 02:15 AM - Forum: KC868-A16 - Replies (1)

Please, I wanted to use the output channel of the A16 to turn on or off the camera when needed. What is the maximum current supported for each mosfet output channel?

  Driver recommendation for 24V LED strip
Posted by: TMaYaD - 04-10-2025, 10:41 PM - Forum: DIY Project - Replies (7)

Hi
I want to control and dim 24v LED strips using a controller like KC868-A4S. I'm looking for any recommendations for drivers.

I've tried Meanwell ELG-200-24B. But it doesn't turn off completely.

Any inputs are appreciated.

  KC868-A4S and meanwell ELG-200-24B
Posted by: TMaYaD - 04-10-2025, 10:25 PM - Forum: KC868-A series and Uair Smart Controller - Replies (3)

I'm trying to use meanwell ELG-200-24B to drive 24v LED drive strips using A4S and the LED does not completely turn off. When I checked, there is ~0.58V across the analog output and ground.

What am I doing wrong?

  IoT Weather Station - Class B
Posted by: egionet - 04-10-2025, 01:26 PM - Forum: Customer project example - Replies (1)

This is an ongoing project, and I plan to deploy the station in a month or so.  This setup leverages class B scientific grade meteorological instruments polled over serial MODBUS.  The controller enclosure's environment is monitored by a Kilcony RS-485 temperature and relative humidity RTU, and barometric pressure is monitored by a BMP280 over I2C.  The code base is in C i.e. ESP-IDF, and a sample implementation is available here.

Telemetry data model:

Code:
typedef struct rpu_telemetry_data_s {
    uint64_t    timestamp;
    struct rpu_s {
        char        network_id[16];
        char        name[32];
        uint32_t    system_uptime;
        uint64_t    reboot_timestamp;
        uint16_t    reboot_counter;
    } rpu;
    struct atmospheric_s {
        float                   spot_wind_speed;
        uint16_t                spot_wind_direction;
        float                   avg_wind_speed;
        uint16_t                avg_wind_direction;
        float                   max_wind_speed;
        uint16_t                max_wind_direction;
        float                   air_temperature;
        float                   relative_humidity;
        float                   dewpoint_temperature;
        float                   barometric_pressure;
        float                   precipitation_rate;
        hyrs2e_precip_types_t   precipitation_type;
    } atmospheric;
    struct ground_s {
        float   soil_temperature;
    } ground;
    struct cabinet_s {
        float   air_temperature;
        float   relative_humidity;
        float   dewpoint_temperature;
        cabinet_door_states_t door_status;
    } cabinet;
} rpu_telemetry_data_t;

Telemetry data is uploaded to ThingSpeak once a minute over MQTT when connected to a Wi-Fi network.

  How to uses sensors with v3 firmware
Posted by: twostar - 04-10-2025, 01:23 PM - Forum: "KCS" v3 firmware - Replies (13)

I'm having trouble using DHT22 sensors with the v3 firmware, with the v2 firmware you just set sensor ID 1, type DHT22 and it worked.  With the v3 firmware it looks like you need to set a GPIO address but there's no indication for what this should be, and trying the first one, 47, bricked the board. How do you set up a DHT22 (or any other sensor) on the 1-wire GPIO ports?

I am using a kincony A16v3 board for my project. I have tried to upload my arduino code to the board. But the code is not uploading. I have powered the board with 12v supply. And have connected the board to my pc via usb type c cable. 

Chosen nodemcu 32s in boards. But its not working. How to check what have gone wrong ?. Or if any further details required, let me know

Question A16v3 low voltage inputs
Posted by: jaydubnz - 04-09-2025, 05:58 AM - Forum: KC868-A16 - Replies (8)

Hi guys,

I have PIR sensors all over the house connected to an old alarm system. The voltage on the NO contacts are between 1.5v to 3v, which I think is too low for the digital inputs 1 to 16 to register as ON.
I know I can connect to the 5 analog inputs, which does detect the low voltage, but I have ~15 sensors. Is there a way to make these low voltage PIR sensors detectable on digital inputs 1 to 16? Without using a ton of dry contact relays haha

Thank you in advance!
