Infinite Industrial Informatics Lt
Sigfox is a communication protocol that is used to read data from sensors through a fixed network of base stations. It works like a low cost “SMS” service. As an end-user, you only need to buy a subscription to connect to the data network operated by SIGFOX. Sigfox employs a proprietary Ultra Narrow Band (UNB) radio technology that enables communication using the Industrial, Scientific and Medical ISM radio band, which uses 868MHz in Europe and 902MHz in the US. It has the advantage of covering larger areas than other fixed local systems.The overall Sigfox network topology has been designed to provide a scalable, high-capacity network, with very low energy consumption, while maintaining a simple and easy to rollout star-based cell infrastructure. The density of the cells in the Sigfox network is based on an average range of about 30-50km in rural areas and in urban areas, where there are usually more obstructions and noise is greater, the range may be reduced to between 3 and 10km.According to the latest numbers, Sigfox has a nationwide live coverage in 6 countries and in 14 other countries it is deploying and rolling out ts network. By end 2018, the ambition is to cover 60 markets.

Solar Light Company Inc.
Solar Light’s NIST-Traceable PMA-Series Analog Sensors represent the pinnacle of accuracy, durability, and selection on the market today. Our sensors measure discrete bands of the electromagnetic spectrum from the UVA, UVB, UVA+B, UVC, Visible Light, and Infrared regions. Both narrow and broad bands are available, to fit any application, including germicidal applications, environmental probes, and sensors for biologically weighted spectra (such as the erythema and CIE action spectra.) Over 135 different sensors are available in a variety of packages to fit any environment, from indoor clean rooms to harsh locations outdoors to 100 meters under water. Please note that Solar Light offers both Digital Sensors and Analog Sensors in the PMA-Series lineup. Select these Analog Sensors if you don’t need a digital display output of the reading, if you will be connecting to your own datalogger, or if you plan to use a voltage source to provide excitation voltage to the sensor and a digital volt or amp meter to read and convert the results. Analog Sensors are typically used as process sensors that are permanently installed to provide ongoing information. Typical current draw is under 1mA. (By contrast, Digital models are typically used as discrete sensors that are portable and located to provide short term information.)

FIM-71 VHF -
Potomac Instruments, Inc.
The Model FIM-71 is a portable, laboratory quality Field Strength Meter designed for rigorous field applications. Combining a calibrated half-wave dipole antenna and a highly accurate tuned voltmeter with a range of 140 dB, the FIM-71 is suitable for practically all types of RF emission measurements in the 45 MHz to 225 MHz spectrum. The operator can switch select wide or narrow bandwidth, peak or average value of TV or pulse modulated signals, AM or FM demodulation, and a meter dynamic range of either 20 dB or 60 dB. A dc analog output voltage, proportional to the meter indication, is provided for driving a chart recorder. A leveled output from the calibrating oscillator is available for measuring cable insertion loss, filter response, amplifier gain, and other signal ratio measurements. The 4-1/2 inch, taut band, mirrored scale meter is calibrated in volts and dB for precise measurements in field or laboratory environments.

FIM-72A UHF -
Potomac Instruments, Inc.
The Model FIM-72A is a portable, laboratory quality Field Strength Meter designed for rigorous field applications. Combining a calibrated half-wave dipole antenna and a highly accurate tuned voltmeter with a range of 140 dB, the FIM-72A is suitable for practically all types of RF emission measurements in the 450 MHz to 960 MHz spectrum. The operator can switch select wide or narrow bandwidth, peak or average value of TV or pulse modulated signals, AM or FM demodulation, and meter dynamic range of either 20 dB or 60 dB. A dc analog voltage, proportional to meter indication, is provided for driving a chart recorder or similar device. A leveled output from the calibrating generator is available for measuring cable insertion loss, filter response, amplifier gain, VSWR, and other signal ratio measurements. The 4-1/2 inch, taut band, mirrored scale meter is calibrated in volts and dB for precise measurements in field or laboratory environments.

Parallax Inc.
Parallax speeds the process of Propeller 2 development through our partnership with MikroE, who has created a family of 850+ Clicks for most I/O functions you may envision. For each of the Click boards stocked by Parallax, you will find a documented Spin 2 code example on our Propeller GitHub Object Exchange. Connect your Click boards to the Propeller 2 Evaluation Board or P2-EC Edge Breakout Breadboard using the #64008 P2 to MikroBus Click Adapter. Light Ranger 4 click is an accurate distance measurement Click board™ based on a ToF (Time of Flight) measurement principle. The FlightSense™ enabled VL53L1X rangefinder module from STMicroelectronics is a complete measurement stack on the chip. It is surprisingly easy to work with, as this highly integrated range finder module exposes only I2C interface, XSH and INT pins to the host controller. It features the invisible Class1 laser emitter, used to emit a narrow band of a harmless modulated light beam in the IR range (940 nm), physical infrared filters and optics to achieve the best ranging performance in various ambient lighting conditions with a range of cover window options. It can measure distances up to 4000mm, with up to 50 Hz ranging frequency.
