About this kit

49E analog hall: north / south and strength. The Analog Hall Sensor Brick is a carrier for the KY-035 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

• 10-bit field level, 512 = no field
• Pole direction
• Contactless knobs and levers
• 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-035 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.

// Analog Hall Sensor Brick (TP-K30): 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 s;

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

void loop() {
  uint16_t v = s.raw();              // 0-1023
  Serial.println(v);
  led::plotBarGraph(v, 1023, Colors::Yellow);
  basic::pause(100);
}

Project: North or south?

The analog Hall sensor tells the two poles of a magnet apart: TinkerPie shows N or S and how strong the field is.

int centre = 512;

  basic::pause(200);
  centre = hall.raw();
}

void loop() {
  int d = (int) hall.raw() - centre;
  if (d > 40) basic::showLeds("X...X.|XX..X.|X.X.X.|X..XX.|X...X.", Colors::Red);        // N
  else if (d < -40) basic::showLeds(".XXXX.|X.....|.XXX..|....X.|XXXX..", Colors::Blue);  // S
  else basic::clearScreen();
  basic::pause(100);
}
