youse can put up to 8 of these buggers on the I2C bus. That is one more than your need. https://learn.adafruit.com/adafruit-mcp9808-precision-i2c-temperature-sensor-guide/overview
Or you can stay with the one you have and use the addressing to read the other 6 you need: https://www.modmypi.com/blog/ds18b20-one-wire-digital-temperature-sensor-and-the-raspberry-pi These devices are all addressed so you can have as many as the addressing scheme will allow. It appears that the ds18b20 should allow quite a few as each one appears to be addressed by the serial number. Here is another nice piece about them: https://cdn-learn.adafruit.com/downloads/pdf/adafruits-raspberry-pi-lesson-11-ds18b20-temperature-sensing.pdf On Tue, Jan 17, 2017 at 11:54 AM, Michael C.
