1. SharkTapUSB Ethernet Sniffer

Feature

Ethernet Test Access Port that does not require an ethernet port, for thin notebook or netbook PCs. Uses USB 3 or USB 2 port on PC (Also provides a CAT-5 TAP port)
A 'Test Access Port' allows you to see the packets on an ethernet link. Directly supports 10-, 100- or 1000Base-T links.
Intended to be used with the open source Wireshark program, or equivalent.
The SharkTap implements what Cisco calls a SPAN port: It is a switch with port mirroring enabled. Also called an aggregating tap. Will *not* route from TAP to network.
Power-over-ethernet pass through. 750mA current. Non-conductive plastic cover. Auto cross-over for cables. USB3 cable included

Description

The newest member of the SharkTap family allows you to sniff an Ethernet link without using an Ethernet port on your PC. This is ideal for newer portables without an Ethernet jack, but is also a benefit if you don't want to switch a port between network and debugging purposes.

2. SharkTap Gigabit Network Sniffer

Feature

The SharkTap is a special purpose ethernet switch that allows you to 'tap into' an ethernet connection. It is intended to be used with the free Wireshark network analyzer or equivalent.
Conventional switches route packets only to the intended destination port, reducing traffic, but preventing a third port from seeing all packets. The SharkTap duplicates all packets to or from the 'NETWORK' ports on the 'TAP' port.
Supports 10, 100 and 1000Base-T, all ports. Power-Over-Ethernet (POE) pass-through on the 'NETWORK' ports.
Powered from a micro-USB cable (included), draws 350mA or less
Other features: Auto-MDIX, so no crossover cables ever needed. Non-conductive enclosure. Will not route packets from TAP to NETWORK ports.

Description

The SharkTap is a special purpose 10/100/1000Base-T ethernet switch that allows you to 'tap into' an ethernet connection. It is intended to be used with the free Wireshark network analyzer or equivalent. If you don't need Gigabit speed or Power-Over-Ethernet, see the B00DY77HHK product.

Video tutorial for your preparation. Please scroll down to "Related Video Shorts" on this page to find out. Also, you can download the latest version of Instruction Manual in the section of Technical Specification, on the same page as product description.

Description

Every now and then, it's a good habit to check out the entire length of a gas line to make sure the pipes haven't developed any small cracks or leaks. Permanent leak detectors are good at monitoring single rooms, but you will need a handheld detector to make sure the entire line is okay. TheSmart Sensor8800LPortable Gas Detector is the perfect choice for quick and easy routine leak checks.

This handheld detector is the best solution for tracking down the source of a leak before it becomes a major problem. A highly sensitive sensor sits on top of a flexible tube that allows you to change the detection direction to hone in on the leak's source. Sound and visual alarms will indicate the amount of gas as you walk around. Given the wide range of gases this unit can detect, it is even sensitive enough for commercial work.

5. Adafruit Bluefruit LE Sniffer - Bluetooth Low Energy (BLE 4.0) - nRF51822 - v3.0 [ADA2269]

Feature

Adafruit Part Number: 2269
Stock Type: Wireless >> Bluetooth
In Stock & Ready to Ship

Description

Interested in learning how Bluetooth Low Energy works down to the packet level? Debugging your own BLE hardware, and trying to spot where something is going wrong? Or maybe you're writing a custom application for your phone or tablet that needs to talk to existing BLE hardware, but you don't know how it works beneath the surface? We have the perfect tool for you!

This Bluefruit LE Friend is programmed with a special firmware image that turns it into an easy to use Bluetooth Low Energy sniffer. You can passively capture data exchanges between two BLE devices, pushing the data into Wireshark, the open source network analysis tool, where you can visualize things on a packet level, with useful descriptors to help you make sense of the values without having to crack open the 2000 page Bluetooth 4.0 Core Specification every time.

Plug it into your development machine, fire up the special sniffer bridge SW, select the device you want to sniff, and it will fire up Wireshark for you and start pushing data in via a live stream (using Nordic's Windows software), or save to a pcap file that you can analyze with Wireshark later.

Please Note : You can only use this device to listen on Bluetooth Low Energy devices! It will not work on Bluetooth (classic) devices. The Nordic Wireshark-streaming sniffer software is currently Windows only. We have example code using the python API that will work on any OS to log the sniffed data to a pcap file for analysis so you can use this sniffer with any OS with python.

The sniffer firmware cannot be used with the the Nordic DFU bootloader firmware, which means that if you want to reprogram this devices you must use a J-Link (and, likely, a SWD adapter + SWD Breakout ) You cannot over-the-air reprogram it.

FIND GAS LEAKS AT HOME:
Find the location of any natural gas, propane, LP or fuel leaks by running sensor probe along a gas pipe, fuel line, or fittings near any gas smells. Pinpoint fuel leaks from your lawnmower or car. Gas leak is found when alarm sounds and LEDs light up. Don't pay a technician's $100+ diagnostic fee when you can find a gas leak anytime with this propane & natural gas detector.

STEPS/TIPS ON USE: (see video on this page)
-To detect leaks while minimizing false alarms, turn the sensitivity dial upward toward (+) until the device begins to alarm away from any gas leak. Turn sensitivity dial downward (-) slightly until alarm stops but the 1st LED remains lit. Now, any small increase of gas level (as from a leak!) will cause the alarm to sound.
-If alarm sounds before finding a leak, sensitivity needs to be decreased to prevent false alarms.
-Each leak varies in leak rate and background gas concentration, so adjusting sensitivity level will help find any leak.
-Allow device to warm up sensor for 10s until yellow "Warm Up" light turns off.

SPECIFICATIONS:
Maximum Sensitivity: 50 ppm
Alarm range: 10%-40% LEL
Warm up time: 10s
Response time: 2s (10% LEL)
