Oregon Scientific Remote Weather Stations

For all tropical plant enthusiasts keeping an eye on the temperature in polytunnels, greenhouses and conservatories is a key factor and on frosty nights or during heatwaves it can be critical. I keep two units indoors, 3 sensors on each one, and check the temperatures in our greenhouses and polytunnels last thing at night and first thing in the morning without having to go outside. On many an occasion this has avoided a disaster. Be safe don't be without one of these useful low cost remote wireless weather stations. Choosing the right product from Oregon is a bit of a minefield, so I have tried to provide as much information as is available, including things that are not obvious from the marketing information!

Radio Controlled Projection Clock RMR966P - Comes with THR128 remote sensor 30 metres 
If like me you wear glasses or contact lenses and cannot see the clock in the morning without putting on glasses, this is for you. It projects large time and temperature numbers on to your bedroom ceiling that are easy to read, displaying the outside temperature also tells you if you need extra time in the morning to defrost your car!  The clock is controlled by the MSF signal from Rugby so it is precise to the minute and adjusts automatically to and from British Summer Time. It tells you the temperature inside and outside and includes a light sensitive night light that switches on/off automatically as it gets dark. I find this a real boon and stops me wandering in to the wardrobe in stead of the bathroom if I have to get up in the middle of the night.

Specifications

  • Rotatable night light switches on/off automatically (light sensitive)
  • Remote temperature display using cable-free sensor (included)
  • Frost Pre-Alarm
  • Second time zone for use abroad
  • Image reversing switch for 180 image flip (if upside down)
  • 180 image rotation for orientation of projected image of time
  • Image rotation drum for orientation of projected image (continuously from 0 to 180)
  • Image focus knob for manual focusing of projected image
  • Tiltable projection head for positioning the projected image vertically (upward or downward)
  • Continuous projection function with mains adaptor (included)
  • Adjustable arm projects the time and indoor/outdoor temperature onto the ceiling at night at the touch of a button.
  • Radio controlled Clock & Calendar
  • Crescendo alarm with snooze
  • Up to 5 display languages
  • HiGlo TM backlight
