    Features and Applications:
    The dry reed pipe is compact and lightweight, and can be installed in extremely limited space, making it ideal for miniaturized equipment
    The dry reed switch components are hermetically sealed in an inert gas atmosphere, never in contact with the outside environment, and have a long working life
    The dry reed pipe does not use sliding elements, so there is no metal fatigue associated with all metal degradation, ensuring virtually unlimited mechanical life
    The reed switch is very good in mobile phones, program-controlled switches, copiers, washing machines, refrigerators, cameras, disinfection cupboards, door magnets, window magnets, electromagnetic relays, electronic scales, liquid level gauges, gas meters, water meters, etc application
    Precautions for use:
    Extreme care must be taken when cutting or bending the lead legs of the reed switch to avoid undue stress and damage to the glass-to-metal seal Proper clamping tools must be used
    Temperature and excessive exposure time can cause damage to the glass-to-metal seal (cracking, leakage, etc), so fast and reliable welding techniques (processes) must be used The recommended welding conditions are: 280-300 °C for hand welding and 250 to 300 °C for wave soldering

    Instructions
    A soil moisture and humidity module most sensitive to the environment , usually used to detect soil moisture
    Modules in the soil moisture reach the set threshold , DO port output high when soil moisture exceeds a set threshold, the module D0 output low ;
    Digital outputs D0 small plates can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting soil moisture ;
    Small plates digital output DO OUR relay module can directly drive the buzzer module , which can be composed of a soil moisture alarm equipment ;
    Small plates AO analog output modules can be connected and AD through the AD converter , you can get a more accurate value of soil moisture ;
