HiGrow ESP32 DHT11

Just got myself this badboy: https://www.aliexpress.com/item/higrow-ESP32-WiFi-Bluetooth-Battery-DHT11-Soil-temperature-and-humidity-sensor-module/32818803204.html

Flashing worked perfect and wifi connection no problems. But now i wonder how am i going to find the pin to read the Temp and humidity from the dht11 ? anyone had this board before? Same as finding the correct pin to read the soil..

Found a few pins from a lookalike project that seems to work.
let ResetPin = 0;
let LedPin = 16;
let DHTpin = 22;
let SOILpin = 32;
let LIGHTpin = 34;

Problem now is that i try to use the DHT11 module do get the correct values but it throws a nasty looking error:

>Guru Meditation Error of type InstrFetchProhibited occurred on core  0. Exception was unhandled.

See here

You might have an earlier firmware that had an issue.

Posted at 2018-02-15 by Gustav

I tried with both 1v95 and 1v94 and none worked. I tried just choosing a different pin aswell, and then i got

{"err":true,"checksumError":false,"raw":"","temp":-1,"rh":-1}

And if i do a normal analogRead on pin 22

>analogRead(22)

Sorry - your information is a little vague if you want help with this!

I tried with both 1v95 and 1v94 and none worked.

Did you get the crash with 1v95?

Posting your code might help.

I tried just choosing a different pin aswell, and then i got

Ok. What pin and did yout try? What are you testing?

For the analogRead see here:

http://www.espruino.com/ESP32#gpio-pins

http://www.espruino.com/ESP32#analog-read-write-example

You should refer to the pins at the D numbers. The pins on the board may be numbered differently. Espruino uses the chip pin numbering for the esp32.

To read ADC0:

>analogRead(D35);
=0

I got the same error with both versions of Espruino.
My code is

    var dht = require("DHT11").connect(D22);
    function onInit() {
        setInterval(function () {
            dht.read(function (a) {
                console.log(JSON.stringify(a));
            });
        }, 3000);
    }
    onInit();

When a try pin D22 i get the error that i posted in the top post. Guru meditation.. When i try randomly reading pin D17 with the DHT11 module i get the answer

    {"err":true,"checksumError":false,"raw":­"","temp":-1,"rh":-1}

When i do a analogRead() On pin D22 i get

E (221702) RTC_MODULE: /mnt/c/Users/rhys/esp32/edge/EspruinoBui­ldTools/esp32/build/esp-idf/components/d­river/./rtc_module.c:554 (adc1_config_channel_atten):ADC Channel Err
E (221707) RTC_MODULE: /mnt/c/Users/rhys/esp32/edge/EspruinoBui­ldTools/esp32/build/esp-idf/components/d­river/./rtc_module.c:581 (adc1_get_voltage):ADC Channel Err
=0.06298828125

Sadly i cannot follow the actual pin to the sensor premounted on the board.. But from a look at other projects they use pin 22.

Posted at 2018-02-16 by Wilberforce

What is the output of analogRead(D35);

This should read the ADC which will be contected to the soil probe.

---

Posted at 2018-02-16 by Gustav

analogRead(D35) reads 0, but from what i know the soil pin is D32 and it works, displays 0.8, when i hold my fingers around it displays around 0.4 so it works.

@gfwilliams
In debug mode build, an Assert is failing here:

HALTING.

    IOEventFlags channel,             //!< The event that fires the callback.

  // Save the callback function for this event channel.
  assert(channel>=EV_EXTI0 && channel<=EV_EXTI_MAX);
  jshEventCallbacks[channel-EV_EXTI0] = callback;
}

EV_EXTI_MAX is defined as: https://github.com/espruino/Espruino/blob/e609b94f83f665c26cf4f86acac068c396427e99/src/jsdevices.h#L54

EV_EXTI15, // External Interrupt 15
  EV_EXTI_MAX = EV_EXTI15,

@jumjum did the setwatch code for ESP32 - so I'm unsure how pin numbers (D22 in this case) is mapping to a channel?

Thanks - let's figure this one out in the issue you filed on GitHub?

Great job guys ! no more Meditation error ! but now i get:

{"err":true,"checksumError":false,"raw":­"","temp":-1,"rh":-1}

When trying to read D22 ? thoughts.. why isnt it recieving any data..
// Edit
Tried with another Dht11 standalone board on pin D22, works like a charm.. You think my onboard sensor is broken ?

---

Posted at 2018-02-19 by Wilberforce

Did you pull the latest firmware and build?

Thanks to @gfwilliams, there is now a fix on the ESP32 if the pin > D15, so this should now work for D22.

The firmware bin file can be fetched here:

http://www.espruino.com/binaries/travis/deee7d431ee31825fab762bf2c7ec2e86b994455/espruino_1v95_esp32.tgz

This is now working:

setWatch(function(e) {console.log("Button pressed",e);}, D22, { repeat: true, edge: 'rising' });
