Your indoor weather station monitor predicted rain in three days, so you didn't water your plants. Now, a heat wave has assaulted your plants for three days. Did you build a weather station incorrectly?
To err is human, to forgive divine, but to really foul things up requires a computer. So says one of Murphy's sub-laws. Weather stations are designed to be 75 percent accurate (most weather forecasters on television would be happy for that success rate). Weather forecasts are based on chanegs in air pressure.
Ah, you say, but when setting up a weather station, I changed my mind and moved a sensor from the roof to the wall.
Moving weather sensors doesn't cause erroneous readings. The most you can do is create variances between two sensors when you move them too close together. Just be sure to keep weather sensors away from paved areas, which can distort readings. Avoid direct sun exposure unless the sensors are solar-powered and/or have a radiation shield. If you've done all this, you shouldn't have any significant errors.
You can be confident when you build a weather station that if the weather report is a mistake, either the computer or, more significantly, the weather is responsible.
