Flood sensor

A method of environmental sensing for use with a) an integrated flood and temperature sensor comprising a ranger tester, a plurality of probes, a temperature sensor, and a level sensor, and b) a wireless network device remote from said integrated flood and temperature sensor, the method comprising:

• measuring an electrical property between two or more of the plurality of probes;
• determining a presence of water from the measured electrical property;
• sensing a temperature with the temperature sensor;
• determining an orientation of the integrated flood and temperature sensor with respect to gravity with the level sensor;
• determining at the range tester if the wireless network device is in range of the range tester including transmitting a range testing signal from the range tester to the wireless network device;
• in response to the wireless network device being in range of the range tester, receiving from the wireless network device a link for communication with the wireless network;
• and
• in response to receiving from the wireless network device the link for communication with the wireless network device, selectively generating a signal indicative of at least one of the determined presence of water, the temperature, and the determined orientation for communication with the wireless network device based on the link.

An environmental sensing device for use with a wireless network device, the environmental sensing device comprising:

• a plurality of probes configured to measure an electrical property between two or more of the probes, and to determine a presence of water from the measured electrical property;
• a temperature sensor configured to measure a temperature near said environmental sensing device;
• a level sensor configured to determine an orientation of the integrated flood and temperature sensor with respect to gravity;
• a range tester configured to determine if the wireless network device is in range of the range tester including transmitting a range testing signal from the range tester to the wireless network device;
• a transceiver configured to receive from the wireless network device a link for communication with the wireless network in response to the wireless network device being in range of the range tester;
• and
• a processor configured to receive said determined presence of water, said temperature, and said sensed orientation, and, in response to receiving from the wireless network device the link for communication with the wireless network device, to selectively generate a signal indicative of at least one of the determined presence of water, the temperature, and the determined orientation for communication with the wireless network device based on the link.
