AMASCHR02 Heating Ring

The AMASCHR02 is an AstroMeters AllSky camera heating ring designed for all-sky cameras and optimized for use with Raspberry Pi camera modules.

Its mechanical concept allows the ring to be mounted directly on the camera module, which simplifies integration and keeps the heating system compact and close to the glass dome that needs protection against condensation.

Autonomous Operation

The AMASCHR02 is designed as an autonomous heater ring, which means it does not require any software configuration during normal use.

The target temperature is selected using simple on-board jumpers. Available preset values are:

• 15 °C
• 20 °C
• 25 °C

Once set, the ring maintains the selected temperature continuously during operation.

Controlled heating is important because it avoids unnecessary overheating of the camera assembly. Excess heating can increase the camera sensor’s readout noise, which is undesirable for low-light imaging. At the same time, maintaining only the required temperature helps reduce unnecessary power consumption.

Power Requirements

The heater ring requires only a simple external power supply:

• Supply voltage: 5-12 V

No separate software control loop is required for standard use.

Intended Use

The AMASCHR02 is intended for applications where the user wants:

• compact heater integration directly at the camera module
• protection against dew and condensation on all-sky camera optics
• straightforward deployment without custom software setup
• stable operation with simple low-voltage power input
• DIY allsky camera setups

Compatibility

The design is optimized primarily for Raspberry Pi camera modules, especially where direct mounting to the camera assembly is preferred.

This compatibility statement refers primarily to mechanical compatibility such as overall dimensions and mounting hole positions.

It has also been verified that the ring is mechanically compatible with other camera modules sharing similar geometry and mounting patterns.
