8. The control method of the wireless sensor controller device according to claim 6, wherein the date recorded by the date and time module is summer time, further comprising step S3,
s3, judging the temperature collected by the temperature and humidity sensor and the summer preset room temperature value:
if T is less than or equal to T2, the wireless sensing controller sends a closing signal to an electric water valve arranged on a branch/water collector or a dry/wet fan coil main line or branch; t is a temperature value acquired by a temperature and humidity sensor, and T2 is a room temperature value preset in summer;
and if T is more than T2, and the closing time of the electric water valve arranged on the water dividing/collecting device or the dry/wet fan coil main line or the branch line exceeds N 'min, wherein N' is a positive number, the wireless sensing controller sends an opening signal to the electric water valve arranged on the water dividing/collecting device or the dry/wet fan coil main line or the branch line.
9. The control method of the wireless sensor controller device according to claim 6, wherein the date recorded by the date and time module is winter time, further comprising step S4,
s4, judging the temperature collected by the temperature and humidity sensor and the temperature value of the room preset in winter:
if T is more than or equal to T3, the wireless sensing controller sends a closing signal to an electric heater arranged on a branch/water collector or a dry/wet fan coil pipe main line or branch;
wherein T is a temperature value acquired by a temperature and humidity sensor, and T3 is a room temperature value preset in winter;
and if T is less than T3, and the closing time of the electric heater arranged on the branch/water collector or the dry/wet fan coil main line or branch exceeds Pmin, wherein P is a positive number, the wireless sensing controller sends a starting signal to the electric heater arranged on the branch/water collector or the dry/wet fan coil main line or branch.
