{"product_id":"pl4-sen-15901","title":"Weather Meter Kit","description":"\u003cp\u003eWhether you're an agriculturalist, a professional meteorologist or a weather hobbyist, building your own weather station can be a really rewarding project. When you're measuring weather, however, you need some pretty specialized sensors. This kit represents the three core components of weather measurement: wind speed, wind direction and rainfall.\u003c\/p\u003e\n\n\u003cp\u003eNone of the sensors in this kit contain active electronics, instead they use sealed magnetic reed switches and magnets so you'll need to source a voltage to take any measurements. The positive side of this is that the sensors are easy to interpret:\u003c\/p\u003e\n\n\u003cp\u003eThe rain gauge is a self-emptying bucket-type rain gauge which activates a momentary button closure for each 0.011\" of rain that are collected. The anemometer (wind speed meter) encodes the wind speed by simply closing a switch which each rotation. A wind speed of 1.492 MPH produces a switch closure once per second. Finally, the wind vane reports wind direction as a voltage which is produced by the combination of resistors inside the sensor. The vanes magnet _could_ potentially close two switches at once, allowing _up to_ 16 different positions to be indicated, but we have found that 8 positions are more realistic.\u003c\/p\u003e \n\n\u003cp\u003eAll of the included sensors are supplied with RJ11 terminated cables, for information on the pin-out of the cable, check out the datasheet.\u003c\/p\u003e\n\n\u003cp\u003e-\u0026gt;\u003c\/p\u003e","brand":"PuriLite","offers":[{"title":"Default Title","offer_id":39690168303797,"sku":"PL4-SEN-15901","price":143.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/15901-Weather_Meter-02.jpg?v=1618122306","url":"https:\/\/getcahits.com\/products\/pl4-sen-15901","provider":"PuriLite","version":"1.0","type":"link"}
