I've been struggling for years on how and where to install a secondary Engine Temp Sensor/Gauge on my 12HT.
We all know that the stock Toyota Landcruiser Temp gauge is a little flakey.
Many people suggested to tap/splice into the top hose but I was very hesitant to do so since it's not really at the engine and is dependant of the thermostat opening to get a real reading.
Not to mention cutting a perfectly good hose and the possibility of more leak points.
Over the past couple years I've been playing with Arduino boards and I came up with a simple solution.
It works very well and is very close reading to what the engine is doing without having to "tap" into anything.
Only cost me around $30.00
Please have a look on what I came up with:
Arduino Nano: Arduino Nano - https://store-usa.arduino.cc/products/arduino-nano?selectedStore=us
OLED Screen: OLED 128x64 Pixel, I2C, 1.3 inch, SSD1306 SH1106, 3-5V - https://www.universal-solder.ca/product/oled-128x64-pixel-i2c-1-3-inch-ssd1306-sh1106-3-5v/
Waterproof Temp Sensor: Digital Temperature Sensor DS18B20 - Watertight - 1 Wire Interface - 3 Meter Wire - https://www.universal-solder.ca/product/digital-temperature-sensor-ds18b20-watertight-1-wire-interface-3-meter-wire/

I hope this inspires you!
