Energy Harvesting Modules 



EH300/EH301 Series EH Modules can accept energy from many types of electrical energy sources and store this energy to power conventional 3.3V and 5.0V electrical circuits and systems such as wireless sensor networks (WSN) using ZIGBEE standards.

These modules capture residual energy as a by-product of a natural environmental phenomenon or industrial process, storing and and conditioning the energy for use at a later time.

The OP07 has very low input offset voltage, like 75 µV and low input bias current like 4 nA and is used in instrumentation applications in the domains of Process control and Test-Measurement.'



The OP07E is specified for operation over the 0°C to 70°C range, and the OP07C is specified over the –40°C to +85°C temperature range.

OP07 - Low Offset and High Impedance Amp

"The accuracy and stability of the OP07, even at high gain, combined with the freedom from external nulling have made the OP07 an industry standard for instrumentation applications."

Low VOS: 75 µV Max and Low Noise: 0.6 µV p-p Max makes it look like an Ideal Op-amp.Voltages like a Wide Input Voltage Range: ±14 V and Wide Supply Voltage Range: ±3 V to ±18 V makes it useful in industrial product design.

Ultralow Offset Voltage - Operational Amplifiers

"OP07 series units may be substituted directly into 725, 108A/308A and OP05 sockets with or without removal of external compensation or nulling components. Additionally, the OP07may be used in unnulled 741 type sockets."

Novato smart sensor transmitter. - 4-20mA Loop-Powered Temperature Sensor with HART

The Novato reference design is a 16-bit, high-accuracy, loop-powered temperature transducer that transmits temperature information from a remote object to the central control unit over a 4–20mA current loop and using the highway addressable remote transducer (HART) communication protocol.



HART Communication Protocol

The Novato reference design fully satisfies the HART physical layer requirements. The HART functions set is developed by AB Tech Solution, an engineering firm specialized in product development services for industrial automation applications.

Established in 1983, Maxim Integrated Products is a worldwide leader in design, development, and manufacture of linear and mixed-signal integrated circuits (ICs).

Maxim circuits "connect" the real world and digital world by detecting, measuring, amplifying, and converting real-world signals, such as temperature, pressure, or sound, into the digital signals necessary for computer processing.

An Excellent way to expand your A/D convertors I/O capability. Multiple Analog Inputs can be routed to a single Opamp or Analog Input of a uC or uP System. Use protection Zeners or clamping inputs.

The 74HC4067; 74HCT4067 is a single-pole 16-throw analog switch (SP16T) suitable for use in analog or digital 16:1 multiplexer/demultiplexer applications. The switch features four digital select inputs (S0, S1, S2 and S3), sixteen independent inputs/outputs (Yn), a common input/output (Z) and a digital enable input (E). When E is HIGH, the switches are turned off. Inputs include clamp diodes.

delabs Notes

This Mux is useful for making a Datalogger or Expanding the I/O of a PLC analog unit. A Multi-Point process scanner, an analog Sample and hold system are some ideas. If you have many testpoints to monitor an you have a Embedded System with one analog input then you could think of this. Remember to protect the inputs and isolate if required. Real world parameters pose real hazards.

The set 4N35, 4N36, 4N37 are popular and versatile optocouplers for isolation of circuit blocks.

The most important feature is the Isolation test voltage 5000 VRMS that means 5KV. But PCB Design is very important to get this isolation for your products too. The PCB area under the



That way Air Insulation makes Isolation good. The Line of Isolation has to be observed in all SMPS under Magnetics and Optos. Creepage of HV can occur due to Grime and Humidity on PCB, use RTV Silicone Rubber or Epoxy impregnation to make your product Industrial or Military Grade. - delabs design Notes

4N35 Optocoupler Vishay

Other Features - Interfaces with common logic families, Input-output coupling capacitance < 0.5 pF, the low level capacitance means you can switch this opto at high speeds.

Opto-Isolaters are used in SMPS to feedback sample of output to control circuits.  In Industrial Automation Boards they are built into Output Modules and most I/O Modules. Isolation is related to Product Safety and Reliability. It protects circuits and systems from real world high-energy exposures.
