The Pax Instruments T400 is a logging thermometer with four thermocouple inputs, USB connectivity, and MicroSD storage. It supports K type thermocouples.
Hardware
- Microcontroller: Atmel ATmega32U4, 8 MHz, 3.3 V
- ADC: Microchip MCP3424
- Junction temperature: Microchip MCP9800
- Screen: 132x64 LCD
Protocol
The T400 outputs CSV data in ASCII format over a USB serial port. Upon device boot or when a new log file is started a header is also output.
Here is a sample of the serial output when a new logging session has started:
v0.14-beta
