Today we're demonstrating 
the ridiculously low power

3
00:00:06.400 --> 00:00:13.960
of NVE's unique AAT001 angle sensors,
by powering a sensor with a tomato.

4
00:00:13.960 --> 00:00:15.320
Here's the circuit:

5
00:00:15.320 --> 00:00:17.620
The sensor is connected to a 'scope.

6
00:00:17.620 --> 00:00:21.220
The sensor is sensitive enough
that we don't need amplification.

7
00:00:21.840 --> 00:00:24.100
We have a copper wire as one electrode,

8
00:00:24.400 --> 00:00:27.200
and a zinc-galvanized nail as the other.

9
00:00:27.200 --> 00:00:29.780
That gives us about a volt--
which is plenty--

10
00:00:29.780 --> 00:00:31.700
and the sensor draws 
less than a microamp.

11
00:00:35.200 --> 00:00:36.300
Here's the demo.

12
00:00:36.300 --> 00:00:38.720
The sensor's on the circuit board.

13
00:00:38.720 --> 00:00:41.120
We have a split-pole magnet
over the sensor.

14
00:00:43.320 --> 00:00:45.480
We hook up the tomato--

15
00:00:45.480 --> 00:00:48.360
we don't even need a very big tomato.

16
00:00:55.080 --> 00:00:59.160
As the magnet turns,
the 'scope follows the angle.

17
00:01:10.860 --> 00:01:15.180
The signal goes away 
when we disconnect the tomato.

18
00:01:19.600 --> 00:01:24.160
The AAT001 has 1.25 megohm 
bridge resistance

19
00:01:24.160 --> 00:01:26.720
for ultralow power consumption.

20
00:01:26.720 --> 00:01:31.840
That means it draws less than a microamp 
when powered by a single tomato.

21
00:01:31.840 --> 00:01:35.840
It has a large output signal--
150 millivolts per volt,

22
00:01:35.840 --> 00:01:39.120
which is more than 
160 millivolts per tomato.

23
00:01:39.760 --> 00:01:42.000
The sensor is also precise

24
00:01:42.080 --> 00:01:44.240
and ultraminiature.

25
00:01:44.240 --> 00:01:46.400
These features make it ideal for

26
00:01:46.400 --> 00:01:49.520
for battery, or vegetable-powered applications.

or to order sensors, magnets, or evaluation kits.

29
00:01:58.160 --> 00:02:00.960
You can get the tomatoes at any grocery store.
