The invention discloses a monitoring measuring and controlling instrument which comprises a dustproof and waterproof outer housing, sensor probes, a power supply, an RF transmitter, a converter, a protective cover, a microphone, a camera, a loudspeaker, dustproof glass and a hanging device, wherein the hanging device is composed of a hanging cup, a vertical rotating shaft and a horizontal rotating shaft. The monitoring measuring and controlling instrument is characterized in that the control circuit of the monitoring measuring and controlling instrument transmits a temperature signal, a humidity signal, an analog current input signal and an analog voltage input signal which are detected by the sensor probes to an A/D converter data acquisition card; and an A/D converter performs signal processing for processing the temperature signal, the humidity signal, the analog current input signal and the analog voltage input signal to digital signals and transmits the digital signals to a central processing unit (CPU) for being processed. The monitoring measuring and controlling instrument can monitor a forest, a marsh, an epidemic area, an environment-polluted area, a natural disaster incidental area and an area which is uneasy to arrive at or cannot be arrived in time by personnel. Furthermore the monitoring measuring and controlling instrument can realize real-time monitoring on engineering construction fields of underground workshop, mine, tunnel, pipeline, etc.
