Feature	ESP (ESP8266 / ESP32)	LoRa (SX1278 / RFM95)	GSM (SIM800 / SIM900)
Primary Function	WiFi + Bluetooth connectivity	Long-range, low-power wireless communication	Cellular (2G/3G/4G) communication via SIM card
Range	Short to medium (up to 100 m indoors, 300 m outdoors)	Very long (up to 5–10 km line of sight)	Global (depends on network coverage)
Network Type	WiFi (2.4 GHz) or Bluetooth (BLE)	LoRaWAN / point-to-point RF	GSM / GPRS cellular network
Data Speed	High (up to 150 Mbps WiFi)	Low (typically < 50 kbps)	Moderate (GPRS ~ 85 kbps)
Power Consumption	Moderate; can be optimized with deep sleep	Very low; ideal for battery-powered IoT	High; requires stable 5 V and > 1 A during transmission
Best Suited For	Smart homes, IoT hubs, WiFi-based sensors, automation	Remote sensing, agriculture, industrial IoT, long-range monitoring	SMS alerts, remote control, vehicle tracking, and IoT in no-WiFi zones
Cost	Low (₹100 – ₹300 typical)	Medium (₹300 – ₹800)	Higher (₹500 – ₹1500+)
Power Source	3.3 V (ESP8266) or 5 V (ESP32 Dev boards)	3.3 V typical	5 V, high current (1–2 A peak)
Cloud Connectivity	Direct via WiFi (supports MQTT, HTTP, Blynk, Firebase)	Needs LoRa gateway or paired receiver node	Connects via cellular network; supports HTTP, MQTT through SIM module
Ease of Setup	Very beginner-friendly (Arduino & Pi libraries available)	Intermediate (requires pairing & antenna setup)	Moderate (needs SIM card and AT command handling)
Example Projects	WiFi temperature logger, IoT doorbell, smart plug	LoRa weather station, long-range soil sensor	GSM alert system, SMS-based motor control, GPS tracker

Passive Buzzer Module 3.3V-5V DC

Filamet is really good

Really good filament with no moisture and printed perfectly

The module is working fine i wished you guys had a soldered one and i think you missed the anntena for this module so make sure to provide one with this module

Delivery and quality

Delivery in one day excellent
Product quality is good
