This soldering project kit features a thermocouple sensor for measuring both extremely high and low temperatures in air or liquids, complete with audible alarms.
Key Features:
- Wide Measurement Range: high temperature measurement range is -50℃ to 450℃ (-58℉ to 842℉), low-temperature measurement range is -20℃ to 60℃ (-4℉ to 140℉)
- High/Low Temperature Alarms with memory function
- Dual Display: Red LED display shows temp/humidity readings
- Versatile Use: Measures both air and liquid temperatures
- Mixed Soldering: Practice both SMD and through-hole components
Great for electronics hobbyists, DIY enthusiasts, or educational use - creates a genuinely useful tool for workshops, kitchens, or science projects.


one LM35 plus RPI Pico and small software can do the temperature measurement nicely, also can set up different Output to drive fan or heater etc…
