Feature(may vary by option.)

●Made in Japan
●Energy Harvest Control Board used in conjunction with TWELITE or TWEITE DIP (below TWELITE)
●Pin header terminal mount, small solar panel AM-5815 Panasonic included (soldering required)
●The energy of the solar panel is stored into the condenser and utilize the energy to operate the radio module for a very short time
●It has a built-in circuit to charge excess energy to a power storage device (electric double layer capacitor), so it can be continuously operated even at night where solar panels are not generated

[Pin header installed]

Description

TWE-EH SOLAR is a power management module to convert light energy into power and use as TWELITE-Twilight power supply. You can use TWELITE-Twilight instead of batteries.

Uses a small solar panel that is large at your fingertips, allowing TWELITE-Twilight to operate on cloudy days or with slight light of indoor light.
The TWE-EH SOLAR(Energy Harvest Solar) can realize a battery-less wireless sensor.

Mono Wireless Solar Power Management Module TWE-EH SOLAR

Description

Power management module that can be used as a power supply for small microcomputer module "TWELITE".

Small solar panel included (soldering required).

Key Features

Collects energy from cloudy days or indoor light and converts into power

The connected TWELITE will work.

Built-in circuit to charge excess energy to a power storage device (electric double layer capacitor).

If there is no light source, it can supply power from the storage device.

Allows you to notify the voltage of your storage device.

External circuits and additional resistance allow for connection to anything other than the included small solar panel.
