About this kit

Waterproof-grade digital thermometer chip, read in C over I2C. The DS18B20 Temperature Brick is a carrier for the KY-001 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.

Features

• -55 to +125 C, 0.0625 C resolution
• 1-wire decoding done inside the brick
• Temperature as int16 (C x 100)
• Plug the kit module straight into the socket – no jumper wires
• One cable to any TinkerPie SENSOR port (I2C), BUS IN + BUS OUT to chain more bricks
• On-board CH32V003 does the timing – your code just reads the result

Specifications

How to use it with TinkerPie

1. Plug the KY-001 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.

// DS18B20 Temperature Brick (TP-K01): 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 t;

void setup() {
  Serial.begin(115200);
  tinkerpie::begin();            // also starts the SENSOR ports (I2C bus Wire1)
  if (!t.begin(tpb::KitSensor::DS18B20)) Serial.println("DS18B20 Temperature Brick not found at 0x08: check the cable to SENSOR 1-4");
}

void loop() {
  float c = t.celsius();
  Serial.printf("%.2f C\n", c);
  basic::showNumber(c, Colors::Orange);   // scrolls the temperature
  basic::pause(1000);
}

Project: Tea is ready alarm

Put the DS18B20 probe in a cup of hot water or tea. When it cools to 60 °C, TinkerPie plays a tune.

}

void loop() {
  float c = t.celsius();
  led::plotBarGraph(c, 100, c > 60 ? Colors::Red : Colors::Green);
  if (c <= 60 && c > 30 && !played) { music::playMelody("C5 E5 G5 C6", 200); played = true; }
  if (c > 65) played = false;
  basic::pause(500);
}
