DESCRIPTION
SPEC's printed sensors offer the performance of the best quality electrochemical sensors at a fraction of the price. SPEC's printed sensors are also ultra-thin, offering easy integration into wireless, portable, and networked solutions. These sensors are ideal for health, environmental, industrial and residential monitoring, because of their high performance, low cost andll size.
The design of a switch mode power transformer will differ depending upon the type of circuit used. There are many variations of switching mode power supplies, but they can be narrowed down to three basic circuit configurations (each also has a mirrored configuration); buck, boost, and fly back. Be aware that the name for the buck circuit varies from industry to industry and from person to person. It may also be referred to as an inverter, d.C. Converter, forward converter, feed forward, and others. There are also unipolar and bipolar (push-pull) versions.
Features :
* non-corrosive
* light weight
* long lasting
* high performance
* long performing life
An additional advance in the case of metal oxide sensor technology is the use of AC rather than DC interrogation of the sensing material.This approach provides complementary atmospheric composition information from the real part and the imaginary part of the sensor impedance and introduces a marked enhancement in terms of sensitivity and selectivity.
The SMS is designed to work with up to 8 metal oxide gas sensors. It has circuits to accurately control sensor heater temperature based on digital control loops. The individual sensor heater 'C resistance and temperature coefficients can be set, and there are a number of heater setpoint algorithms that can be selected as parameters.These include temperature ramps, timed temperature schedules and control by an external RS485 interface.Temperature setpoint algorithms can be set in pairs, or slaved to the first pair as required.
The SMS unit measures the impedance of the sensing element by applying a controllable synthesised sine wave to a potential divider formed by a top resistor (selectable between 100kR and1MR by an on-board jumper) and the sensor:
The sensor resistance is displayed by the PC monitor software, as is a measure of the quadrature (reactive) component.
Specification

digital control of heater temperature using an adaptive algorithm and a number of heater temperature profiles to aid selectivity.

EKO Heat Flow Sensors are suitable for the direct measurement of heat flow inside materials, and the measurement of the radiant flow emitted by bodies such as refrigerators and containers.
Principle of thr measurement
There are three modes in heat transmission,thermal conduction, radiation and convection. If the heat flow sensor is placed on the surface of the material, it measures the total value of those three modes. If the sensor is placed inside the material, it directly measures the heat transmission caused by thermal conduction.

The unit deploys four electrochemical sensors, an NDIR CO2 sensor and a laser particle monitor. These combine with a temperature and relative humidity sensor, and GPS is used for accurate location and timestamping.There is also an optional microphone to provide ambient noise information. Data is stored locally and uploaded to a central management site.

1.General description
The luminox family (lox) is a range of factory calibrated oxygen sensors which measure ambient oxygen partial pressure (ppo2) levels using the principle of fluorescence quenching by oxygen.
By default luminox measures ppo2 (mbar) and temperature (°c). An optional pressure sensor enables luminox to also measure barometric pressure (mbar) and to convert the ppo2 reading to an oxygen concentration (o2%).
The sensor benefits from low power operation, traditionally associated with electrochemical sensors, while providing a much longer lifetime due to the non-depleting sensing principle.
Luminox is ppo2 and temperature compensated, enabling accurate operation over a wide environmental range without the need for additional system components. Unlike other sensor technologies, luminox is very stable and robust, does not contain lead or any other
Hazardous materials and has negligible cross sensitivity to other gases.
2.Cleaning
The housing of the sensor can be cleaned using a damp cloth. The sensor should not be immersed in any cleaning media.
Full application and technical support can be provided by our knowledgable and highly experienced engineering team if required.

Description
The ngm2611 is a pre-calibrated module for natural gas alarms which is precisely
Calibrated in figaro's humidity and temperature controlled facility.
The most important process in manufacturing reliable resdential gas alarms is
Adjusting the alarm point. Calibration is a complicated and time consuming
Process which also requires a substantial investment in calibration equipment. By
Eliminating the costly calibration process, this module enables users to easily and
Simply manufacture residential natural gas alarms. Figaro has taken the complexity
Out of designing a gas detector circuit by providing users with a temperature
Compensation circuit which combines a built-in thermistor and individually adjusted
Load resistor together with figaro’s low power methane gas sensor.
A connector allows easy replacement of the module for the purpose of periodic
Sensor renewal. This input/output connector enables easy installation of the
Module into the gas detectors’ mother board. This same mother board can be
Used for both methane and lpg gas detectors by simply changing the module.
This module is designed to meet the performance requirements of en50194, and ul1484.
Please refer to “technical information for tgs2611” for sensor sensitivity characteristics.
Refer to “application notes for tgs2611” for further information regarding circuit design.

· Lead free sensor, reflow solderable
· Low power consumption
· Fast response time and very low temperature coefficient
2.Description
HTU21D, the new humidity and temperature sensor of MEAS is about to set new standards in terms of size and
intelligence: Embedded in a reflow solderable Dual Flat No leads (DFN) package of 3 x 3mm foot print and 1mm
height it provides calibrated, linearized signals in digital, I²C format.
HTU21D sensors are dedicated humidity and temperature plug and play transducers for OEM applications
where reliable and accurate measurements are needed. Direct interface with a micro-controller is made possible
with the module humidity and temperature digital outputs. HTU21D sensors are low power consumption
designed for high volume and cost sensitive applications with tight space constraints.
Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic

HTU21D sensor can be changed by command (8/12bit up to 12/14bit for RH/T), low battery can be detected and
a checksum improves communication reliability.
With made improvements and the miniaturization of the sensor the performance-to-price ratio has been
