DETAILED DESCRIPTION

[0035] Example 1

[0036] like Figure 1 , Figure 2 As shown, a quick-plug grain condition detector for a grain storage warehouse includes a sensor 3, a transmission cable 2 and a hollow detection pole 1. The transmission cable 2 and the sensor 3 are both arranged in the detection pole 1. There are multiple groups of sensors 3. The multiple groups of sensors 3 are connected and arranged on the transmission cable 2 along the axial direction of the transmission cable 2. Each group of sensors 3 includes at least a temperature sensing device and a humidity sensing device.
