New Sensor I Found

[EDIT] In this thread, there may be broken links as time goes on. The purpose of the posts is to give members ideas to build on and be a repository for other people to add to as well. Happy building!

Well its new to me. I can see it now. "Dave, there seems to be an approaching storm. It's time to stop our soccer game and get inside":D eBay Link, Datasheet Link

--------
Franklin Lightning Sensor provides early warning indication of lightning
storm activity within a 40km range
- Provides distance estimation to the head of the storm
- Detects both cloud-to-ground and intra-cloud (cloud-to-cloud) ashes
- Intelligent algorithm provides for false disturber rejection
- Programmable detection levels enable threshold setting
for optimal con gurability
- SPI and I2C interface is used for control and register reading
- Automatic antenna tuning
- Supply voltage range 2.4 to 5.5V
- Power-down, listening and active mode

Here is another one for motion detection for up to 20 meters. *eek*

Edit: see post #6 for better one.

UPDATE: Here is another lightning detector that popped up.

How about this one? It looks small enough.

Technical Specifications:
-------------------------------
Active area : 5mm Circle x 38mm
Actuation Force: ~0.2N min
Force Sensitivity Range: ~0.2N - 20N
Ideal Operating range (90% or more of resistance change occurs between):10gf ~ 1.0kg (0lbs ~ 2.2lbs)

It could work depending on the size of the claw or hand you are using

Love the sensors thread.

If I run across anything interesting I'll post it up.

Always looking for more goodies for R2.

@Lumpy By all means! There are a lot of sensor variations on the same kind but I try not to post well known ones. For instance I only put up the PIR sensor because it has a detection angle of 180 degrees. There are a lot of gas sensors out there but I havent posted them. I'm not sure many people are going that route.

I've put this other laser range finder in other threads but I noticed it isnt on this one. Here goes!

Troy,

Thanks a lot. A appreciate these updates. I check them often.


Here's a cool one using Nitinol AKA Flexinol as a sensor and actuator:


Best,

Bill

A couple new ones. Although capacitive sensors aren't new, these seem handy as a multi-button input device.

I imagine these would have to be mounted backwards with the flat side against the inner plastic wall of your bot and use some decals on the outside.

I've seen these forever but I thought I posted them on this thread. I guess not so here it is.

The Scio is really cool. With ez-robots ability to be wifi connected and store data in a database, this really would be an amazing addition to a robot project. Thanks for sharing Troy!

I am somewhat skeptical of SCiO. I'll wait until they are actually shipping next year and I see some independent reviews. I would love to have a device that could tell me when fruit is ripe or starting to rot by "sniffing" the molecules it emits (and any number of other cool functions), and I think we are within a few years of that kind of technology being available, I am just not sure that SCiO has actually developed it.

wow, this is just like the tricorder spock used in Star Trek
#45  
Yeah I was skeptical but since they say that have a working prototype and all that money from kickstarter it may actually come to the market. It's a neat idea regardless.

The technology of the SCiO is based on light the science for it has been around for over 100 years now and its how we know what stars are made of and because its works with light the SCiO would only react to the surface of an object its light is reflecting off.

Its a cool little
Spectrometer

I would LOVE to have one

The dust sensor mentioned a little bit ago would be funny to use.
