NB-IoT HAT for Raspberry Pi, Based on SIM7020E, B1/B3/B5/B8/B20/B28 Bands
Applicable Region
SIM7020E is mainly applicable in Europe, Asia, Africa, Australia.
Please check the supported bands according to your local service provider when placing order.
Overview
This is an NB-IoT (NarrowBand-Internet of Things) HAT for Raspberry Pi, controlled via serial AT commands, supports communication protocols like LWM2M/COAP/MQTT, etc. Due to the advantages of low delay, low power, low cost, and wide coverage, it is the ideal choice for IoT applications such as intelligent instruments, asset tracking, remote monitoring, and so on.
Raspberry Pi connectivity, compatible with any revision
Support communication protocols such as LWM2M/COAP/MQTT/TCP/UDP/HTTP/HTTPS, etc.
The Metal Detector is a handheld metal detector designed to pinpoint metal (ferrous and non-ferrous) objects during the treasure recovery process.
This metal detector is designed to be used in conjunction with ground search metal detectors to help recover metal targets.
The metal detector has sound and vibration alarms to indicate the presence of metal objects. When the metal detector is close to the metal target, the alarm intensity will increase.
With the precise positioning of the tip and the scraper blade with side scan function, the metal detector can easily detect metal objects very effectively.
LED flashlight can help in dark and low light conditions.
Parameter:
The sensitivity distance for detecting one-yuan coins is greater than or equal to 3.5-5cm, and it has an undervoltage indication function.
