Wind Sensor Rev. P - Low Cost Anemometer. Description The Rev.
P6 wind sensor is the latest revision of our wind sensor. The revisions are mostly tweaks for stability and accuracy. Thermocouples Made From Ordinary Copper and Steel Wire. Thermocouple loop made into a coil can deflect a compass needle.
DC current probe meters are certainly not found everywhere but a compass can be used to indicate current flow by making the thermocouple loop into a coil. This coil uses 5 feet of copper wire but the use of 12 gauge keeps the resistance low enough for observable current to flow. The compass needle is most easily deflected when it is perpendicular to the coil axis as shown in the above picture. A piece of tissue paper was placed over the mirror in the compass case to eliminate lighting glare while taking the photographs. A flame held under one junction will cause an easily observable deflection of the compass needle.
GCDC B1100-1 Barometric Pressure Data Logger. General The B1100-1 uses a high precision digital sensor that makes the B1100-1 suitable for altitude measurements, vertical velocity indication, and weather monitoring.
Data is recorded at a user selectable rate ranging between 10 Hz to one sample per day. The B1100-1 can be programmed to start and stop at specific times each day. Leap Motion.
