ABSTRACT:
A temperature detecting device employing as a temperature detecting element a CdInGaS.sub.4 compound semiconductor material. The temperature of a body in thermal contact with the temperature detecting element is determined using either a reflecting or an absorbing technique. CdInGaS.sub.4 semiconductor material used as a light detecting element provides a temperature measuring range of about -200.degree. C. to about 400.degree. C.
