About this kit

Room temperature and humidity in one module. The DHT11 Temp & Humidity Brick is a carrier for the KY-015 module from common 37-in-1 sensor kits: plug the module into the socket and connect one cable to a TinkerPie SENSOR port. A small CH32V003 processor on the brick does the timing work, so your program simply reads the result over I2C.

How to use it with TinkerPie

  1. Plug the KY-015 module into the 2.54 mm socket on the top edge. Match the pin names: the brick says S + -, the module has the same letters.
  2. Connect BUS IN to any TinkerPie SENSOR 1-4 port with a 4-pin JST-PH cable (the same cable as the other sensors).
  3. More bricks? Plug the next one into BUS OUT. Two bricks of the same type need different addresses: bridge ADDR +1, +2 or +4 on the back (0x08-0x0F; the first is 0x08).
  4. Install the TinkerPie and TinkerPieBricks Arduino libraries, open the quick-start sketch below, choose the board ESP32S3 Dev Module and upload.

Libraries: TinkerPie and TinkerPieBricks (Arduino IDE: Sketch → Include Library → Add .ZIP Library). Full guide: getting started with TinkerPie Bricks.

Quick start

Upload this, open the Serial Monitor at 115200 baud and watch the TinkerPie matrix.

Quick-start sketch (Arduino C++)
// DHT11 Temp & Humidity Brick (TP-K11): quick start
// Reads the brick and shows the value on the TinkerPie matrix and in the Serial Monitor (115200 baud).
#include <TinkerPie.h>
#include <TinkerPieBricks.h>
using namespace tinkerpie;

tpb::KitSensor dht;

void setup() {
  Serial.begin(115200);
  tinkerpie::begin();            // also starts the SENSOR ports (I2C bus Wire1)
  if (!dht.begin(tpb::KitSensor::DHT11)) Serial.println("DHT11 Temp & Humidity Brick not found at 0x08: check the cable to SENSOR 1-4");
}

void loop() {
  if (dht.error() == 0) {
    Serial.printf("%.1f C  %.0f %%RH\n", dht.celsius(), dht.humidity());
    basic::showNumber(dht.humidity(), Colors::Cyan);
  } else Serial.println("DHT11 not ready yet");
  basic::pause(2000);
}

Project: Room comfort meter

TinkerPie smiles when the room is comfortable (20-28 °C and 30-65 % humidity) and frowns when it is too hot, cold, dry or damp.

  }
