Reliable Honeywell Whole-House Humidifiers work with your homes furnace to maintain a proper, comfortable humidity level throughout the home. Honeywell's H8908B Humidistat provides automatic low voltage control of humidifiers in central heating and air conditioning systems.
The Meade TM005X-M Wireless Thermo-Hygrometer is an easy-to-read and economical way to track temperature and humidity in your home or office. Featuring a jumbo display unit with one-inch tall digital numbers, this sleek silver and black unit can monitor up to three remote locations. The TM005X-M comes with one remote sensor, but two additional sensors can be purchased separately and added. With the main display unit measuring 4.33 by 4.86 by 1.08--inch ;W by H by D , and a display that includes comfort and trend indicators, you can place the TM005X-M on your desktop or hang it from a wall. With the remote sensor, you can track the temperatures of pools, hot tubs, spas, ponds, soil, and much more. The remote sensor has a transmission range of up to 100-feet. With the sensor powered by two AA lithium batteries, the unit has an outdoor temperature range of minus 38 to 158-Degree fahrenheit , and when the sensor is powered by two AA alkaline batteries, the range is minus 4 to 158-Degree fahrenheit . ;The two AA batteries required for the sensor, and the two AA batteries required for the main unit, are not included.
Indoor Digital Hygro-Thermometer
This is a simple water sensor ,can be used to detect soil moisture .Module Output is high level when the soil moisture deficit,or output is low.Can be used in module plant waterer device, and the plants in your garden no need people to manage
WINGONEER® trademark Reg.NO:4747611
Interface Description (4-wire):
DO: digital output interface (0 and 1)
AO: analog output interface
Instructions for Use:
Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.
The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture.
The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment.
Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture.
