Those of you that are looking for a temperature datalogger may be interested in a new piece of kit which has arrived at the Adafruit website this week in the form of the Pax Instruments T400 Temperature Datalogger.
The Pax Instruments T400 takes the form of an open source four channel thermocouple temperature datalogger, that is based on the Arduino Leonardo platform which enables it to be hacked to your exact needs if required, but is also ready to use straight out of the box if preferred.
The PAX T400 has been designed for both professionals and hobbyists and measurements can be logged on the included microSD card. The T400 is capable of being used for live thermal process monitoring either in the lab or when you are out in the field. Adafruit explains more :
Readings can be saved to a microSD card in standard CSV format for processing in Microsoft Excel, LibreOffice, or your favourite data analysis tool. Readings can also be captured live via the USB serial port. This is perfect for live process monitoring in lab experiments or connecting to an internet-enabled device.
Specifications include :
– The T400 runs on the ATmega32u4 AVR processor.
– The MCP9800 temperature sensor is used for cold junction compensation.
– The MCP3424 analog-to-digital converter measures the voltage produced by each thermocouple.
– The DS3231 real time clock is used to trigger readings. Between readings the device is put into low power sleep mode. The RTC wakes up the unit to take a reading. This gives a longer battery life.
– The T400 uses a standard BL-5C battery. This is great for battery replacement in the field.
– The generous 132×64 LCD is capable of displaying the current temperature for each thermocouple as well as a graph of the most recent readings.
– Thermocouples connect via standard mini thermocouple connectors. The T400 is compatible with a wide variety of K-type thermocouple sensor types from stainless steel probes to rolling surface-contact sensors.
The Arduino compatible Pax Instruments T400 Temperature Datalogger is now available to purchase priced at $175 from Adafruit. If you liked this you might also be interested in building an Arduino wind speed meter.
