The RDing TEMPer is a USB-based temperature logger.
See RDing TEMPer/Info for more details (such as lsusb -vvv output) about the device.
Hardware
- Main chip: Tenx TMU3101MS (datasheet)
- The markings were removed, but we're relatively sure it's this chip, due to lsusb and pin/feature matching (see below).
- Temperature sensor: Fairchild FM75 (datasheet), I2C slave address 0x4f
- I2C EEPROM: Unknown, yet (markings were removed), I2C slave address 0x50
- Oscillator: 6MHz
Chip pinouts:

See these example sigrok captures for the I2C, USB, and LED traffic going on while the device is queried from the PC (see also screenshots on the right-hand side).
