reading conclusions

In 1994 Yamatake-Honeywell in Japan has developed a Comfort Sensor TY4700. This comfort sensor measures the four physical variables and send it to the control unit. How they get the human parameters : activity and clothing is not mentioned. Later I downloaded the TY4700A Specification from their website, but more about device installation. I'm not sure whether this device has PMV as output, or it measures only the physical variables for PMV calculation.

In 1995 LG Electronics Research Center in Seoul has designed and fabricated a silicon-based TCS (thermal comfort sensing) device. The 4 inch sensor measures air temperature, radiation, humidity and air flow at once, human parameters are not measured but just added for the calculation.
